What You Need to Know About Car GPS Units

If you’ve been comparing car GPS units, you may have already noticed just how complicated it can be to find one that’s right for you, no matter how tech-savvy you might be. Hopefully, after reading this article, you’ll be a bit more well informed about what you need to know to find the perfect unit for you and your budget.


If you haven’t already been shopping around, you may not know that all car GPS units essentially do the same thing: they show you where you are and tell you how to get to where you’re going. They also all come with a variety of pre-programmed destinations, called POIs (or, Points of Interest) to make getting where you need to be even easier. All you need is a finger, because all car GPS units utilize touch screen technology.


What makes finding the perfect one for you so complicated is all the extra features manufacturers are including in their products to meet market competition. Before you get too overwhelmed, let’s talk about these manufacturers and compare the products they’re making.


Although several companies produce car GPS units, I’d suggest sticking with the top three: Magellan, Garmin, and Tom Tom. Sure, there are other companies, like Lowrance, Mio, and Pharos. But all these other companies are competing for only 10% of the U.S. market. It may be a personal thing, but I’ve always liked to go with industry winners. Certainly other companies are making quality products, but I like to know that my purchase will be supported year to year.


Magellan was one of the original companies to start manufacturing GPS devices. With a great company name and a wide selection of products, Magellan is a good choice. I really like their Maestro series, which ranges in price from 0 to 0. You can get a Maestro 3100 for less than 0. That’s not their best buy, though. If you just want an entry level GPS, then Garmin’s nuvi 200 is probably a better bet. Magellan’s best buy is their Maestro 4250, which can do everything Garmin’s competing product can, but for less.


Magellan also has a great deal for AAA members that makes the AAA Tour Book available right inside the device. Of course, you must be a member, but if you’re a frequent traveler, it’s an excellent deal.


With almost 50% of the total market, Garmin is the industry leader. A basic Garmin, the nuvi 200, costs only 0. However, if you’re looking to spend a lot more, you can purchase the 880 model, which includes a lot of extra features, for around ,000. There are no real competitors at the high end of the market place, that is for automotive GPS systems.


Catching up to Garmin is Tom Tom, a company that offers a great selection of products at very competitive prices. For example, what you’d pay for Garmin’s basic nuvi 200 could also get you Tom Tom’s One 3rd Edition, which has a lot of extra cool features. Tom Tom’s GO series has more features and is a direct competitor with Garmin. Tom Tom is currently taking market share from Garmin by offering more features at a smaller price. Tom Tom is no slouch as a company, either. They totally dominate the European market!


Whether you want to spend a lot or a little, comparing car GPS units can be tricky. Continue checking out informative websites so you can find the system that’s right for you and won’t break your budget.

Compare GPS Models To Get The Right Choice For You

When I got bitten by the GPS bug, I decided to compare GPS systems to see which would be the best for me. I only had a vague idea of what these remarkable devices did. I knew they were essentially electronic maps, but I had no idea how they worked, or what was important to look for when buying one. So, I decided to do some research.


My first stop was Amazon to check out their best sellers. (Just click on my link below to see the same information.)


I quickly saw that Garmin, Magellan, and Tom Tom dominated the market. Garmin, I had heard of Magellan and Tom Tom, I had not heard of. My elation at seeing who were the best sellers for GPS units was soon crushed by an overwhelming sense of confusion as I clicked on each item, read its description, and tried to make heads or tails out of the differences between the units.


There must have been some pretty big differences, I thought, because the prices ranged from a low of about 0 to almost 00 for portable units-the kind you can stick to your windshield and remove to take with you when you’re out of the car.


Well, suffice it to say, I did an enormous amount of research and became an expert of sorts.


To save you some time and frustration, let me tell you the basics of what I found out.


Although there are several manufacturers of portable automotive GPS systems, the three main ones are Garmin, Magellan, and Tom Tom. Garmin sells about half of the automotive GPS systems in the world, but Tom Tom is quickly catching up. All three companies make a good product, it’s just that understanding the differences between the three manufacturers and their specific products is a little difficult.


Garmin has two main lines of automotive GPS systems, the Nuvi and the StreetPilot. The functionalities of each line overlap quite as bit, so does their price.


In general, the Nuvi’s are sleeker, more compact units. Their interface (how you use the system) is not quite as straightforward as the StreetPilot’s interface. Garmin Nuvi’s come in a broad price range, from less than 0 for the Nuvi 200 to almost 00 for the Nuvi 770. Per price point, Nuvi’s generally have a few more features than StreetPilots.


The main difference between the Nuvi’s and the StreetPilots, however, are these-according to Garmin, Nuvi’s have a high-sensitivity receiver, whereas StreetPilots do not. Nuvi’s weigh about half as much as StreetPilots. (None of these units is heavy, just StreetPilots weigh almost 10 ounces, where Nuvi’s weigh slighlty more than 5 ounces.


The biggest difference between the two units is the user interface. The StreetPilot “c” series was made expressly to be very intuitive and user friendly. This is not to say the Nuvi’s are not, they’re just not super simple, like the StreetPilots.


Tom Tom has devices that directly compete with Garmin’s. The Tom Tom One, for instance, is comparable to the Garmin Nuvi 200, Garmin’s entry level product. Both are basic GPS systems which come pre-loaded with maps, have touch screen, and voice instructions. The Tom Tom One has a battery with only 2 hours average life, where the Nuvi’s battery will last an average of 5 hours.


To my mind, the Tom Toms are not quite as sleek looking at the Nuvi’s, although their quality seems to be comparable.


Magellan does not have the market share of Garmin or Tom Tom, but they still build a good product. The Magellan Maestro 3100 is a big seller on Amazon. In both price and features, it’s comparable to the Tom Tom One and to Garmin’s lower priced units, both in size and weight. Magellan says their battery lasts up to three hours, fifty percent better than the Tom Tom’s.


One of the biggest differences between the cheaper GPS systems and the more expensive ones is the number of “Points of Interest” in the unit’s database.


Points of interest are preloaded hotels, restaurants, business locations, hospitals, basically anywhere you might like to go, which are included in your devices database. The Magellan Maestro, for instance has 750,000 points of interest. The Garmin Nuvi 200 comes with approximately 6 million!


If you’re going to use your GPS for traveling, having more points of interest available might be a key feature, and when you consider the distances involved, 750,000 items is just not that many.


Another feature I think is important is Bluetooth technology. Your higher priced units can work as a cell phone (both making and receiving calls). It’s hard enough (and even illegal in some areas) driving and talking on your cell phone. Add looking at your GPS to that mix, and…well, you might want to pull to the side of the road. To my mind, the fewer devices to keep up with the better.

GPS Review – What To Look For

It is more than difficult to find a good GPS review on the Internet. The reason is this: GPS devices all do the same thing. They show your location on an electronic map, and then show you how to get where you’re going. Now, by GPS device I mean a car GPS device that you buy separately from your automobile and either hang from a bracket on your windshield or put next to you on the seat.


So, the key to a good GPS review is understanding the features that various GPS devices offer at each price point.


What do all GPS devices have in common?


All car GPS devices that are on the market today have a touch screen where you can enter information into the unit, such as your destination address. All auto-calculate the route to that address, and all give you spoken directions of some sort as you drive to your destination. In addition to this, virtually all GPS devices come pre-loaded with maps, usually at least of the continental United States, have an internal battery for emergency use, and can toggle between 2D and 3D map views. (3D gives you a slightly more realistic view of what you should be seeing in front of you.)


There are exceptions to all of these rules, but almost all are in the older models.


Who are the industry leaders?


There are three main manufacturers of car GPS systems, Garmin, Magellan, and Tom Tom.


Garmin sells about one out of two of all the car GPS systems sold in the world. They are known for making a quality product. Magellan was an early leader in GPS systems that can route you to more than one destination. They do not have nearly the market share that Garmin has. Tom Tom is a late arrival who is quickly catching up. According to Tom Tom, their GPS system, the Tom Tom One, is the best selling system in the world.


What are the main features to look for in a GPS system?


In this GPS review, let’s start at the cheap end and work our way up.


You can buy a GPS system for less than 0. The Garmin nuvi 200 and the Tom Tom One, 3rd Edition currently sell for less than 0 at Amazon.


As you increase price, the main features you can add are


Voice prompts that actually say the street name


Cheaper GPS devices only tell you where to turn. They say something like, “Turn right, here.” A good feature to be aware of is having the GPS device actually say the street name of the road you need to turn on. So, instead of “Turn right, here,” a better GPS system would say, “Turn right on Highland Avenue,” or “Take a left onto the entrance to I-95.” Devices with spoken street names usually start around 0.


Another feature to look out for is real-time traffic and weather capability


Wouldn’t it be nice if your GPS device could not only tell you how to drive from Atlanta, Georgia to Charlotte, North Carolina, but could alert you to bad traffic conditions in time to take a detour? Well, many of the more expensive units can. How does your GPS device know what the traffic is like up ahead? GPS devices that have this capability are tuned to either an FM or satellite radio frequency that broadcasts this information. If your device has this function, then it will usually come with a free trial subscription to this service. After that, it’s going to cost you, but the cost is fairly low, especially considering how useful real-time traffic is. Along with real-time traffic usually comes real-time weather — an added bonus.


Any of the Garmin nuvis from the nuvi 350 up have FM traffic capability. The nuvi 350 runs slightly less than 0 at Amazon. If you want a Magellan that route you around hold ups, you’ll be paying 0 to 0. All of the Tom Tom’s have this capability, even the Tom Tom One, 3rd Edition, which is one of the cheapest units on the market, currently running around 0.


Do you regularly use your cell phone while driving?


I know I do. It’s problematic to hold the cell phone in one hand and negotiate your way through heavy traffic on a busy interchange. If your phone supports Bluetooth technology you can get a GPS receiver with that same capability and actually use it to make and receive calls. You answer an incoming call by just tapping on the touch screen. You make an outgoing call by either entering the number in your GPS’s touch screen key pad or by accessing numbers stored in the device — downloaded from your phone when you first set up your receiver. So, now instead of wearing that silly Bluetooth headset and looking like a member of the Borg Collective, you can just have your GPS device do double duty. If you make a lot of calls while driving, this is definitely a feature you need to think about.


As to what Bluetooth is going to run you, the Garmin nuvi 360 is their lowest priced Bluetooth model. It currently sells for slightly more than 0. Virtually all of their upper end products have Bluetooth. Two of the Magellan Maestro series, the 3250 and the widescreen version, the 4250 have Bluetooth. They run around 0 and 0 respectively. The Tom Tom GO series has Bluetooth. They run anywhere from 0 to 0.


Multi-destination routing


It’s not something that I use much, but it’s definitely worth knowing about. Multi-destination routing means you can enter multiple routes into your GPS at one time and it will calculate the best route that includes all of your destinations.


Garmin’s nuvi 700 series does this, as well as a couple of their StreetPilot series. Most of the Magellan Maestro series does this – they can be programmed to hold up to 20 separate destinations. As for Tom Tom, the GO 510 can hold up to 15 routes. As to price, the nuvi 700s run anywhere from mid-0s to almost 0. The Magellans are slightly less expensive, running from mid-0s to the mid-0s. The GO 510 costs slightly less than 0 at Amazon right now. The voice prompts, Bluetooth, and multi-destination routing are three of the more important features to consider.


Also, you want to keep in mind what maps your device comes with. And, almost as important, how many preprogrammed Points of Interest are included in its database.


Points of Interest


(POIs) are names, addresses, and phone numbers of possible destinations, anything from the nearest Starbucks to Yellowstone National Park. The lower priced units come with less than 1 million POIs. That’s not enough, if you’re going to be using this feature. For use outside of your normal travel routes, you really want a few million POIs. Virtually all GPS devices now come with this, except the lowest prices models, like the Garmin nuvi 200, which only has regional maps and less than 1 million POIs. (There’s nothing wrong with fewer POIs, if you’re not planning on needing them, but they sure can come in handy.)


Yet another feature to keep in mind is screen size. The standard size is 3.5 inches. This is measured on a diagonal. So the screen for the nuvi 270, for instance, measures 2.8″ by 2.1″. The so called widescreens measure 4.3 inches on the diagonal. You’re actually getting 70% more screen this way.


Why is screen size important?


It has to do with ease and safety of use while driving. Personally, I like a wide screen, but then again, my car is fairly big and has a big windshield. The difference in price between a regular screen and a widescreen is about . That might be money well spent. On the other hand, if you drive a smaller vehicle with less windshield area, the wider screen might be more of a hazard than a safety feature.


Currently at Amazon, Garmin nuvis (their newer product line) run from 9 for the nuvi 200 to 9 for the nuvi 770. The Magellan Maestros are running from 8 for the 3100 to 6 for the widescreen 4250. Tom Tom’s GPS systems are currently priced from slightly less than 0 for the Tom Tom One, 3rd Edition, to 9 for the GO 700 (which is overpriced).


Whatever you do, don’t procrastinate. Even with a good GPS review, with all of these confusing choices it’s tempting to just wait for whatever the next model is going to be. What you’re missing by doing that is lots less stress while driving! Imagine, if you’re a guy being able to always (really) know where you’re going despite what your wife or girlfriend says. And, even better, if you’re a woman you won’t have to pester your husband or boyfriend to stop at the local gas station and admit that they’re lost – not an easy admission for a guy. (I should know!)

GPS Systems that Magellan Would be Proud of

Ferdinand Magellan was the Portuguese explorer who was the first to sail around the world with his crew. He is the guy who also gave the Pacific Ocean its name. Magellan also had the unfortunate assignment in the early 1500s of finding a water route through South America. If he would have had a GPS device packed in his trunk along with his feather hat and tights, he could have been saved a lot of time and trouble. Today, we have an invention that would make Magellan proud, and one of the companies that manufacture these devices shares his name. The GPS systems made by Magellan are top of the line instruments that keep people all over the world from getting lost.


GPS systems are capable of pinpointing your location while you are driving in your car either on Route 66 cross-country or in the middle of the world s largest city. Units that are made to sit on the dashboard of cars usually plug in to the car s cigarette lighter adapter, and have brightly colored screens and tons of helpful functions to help you on your way. The handheld units are portable and even though they have a smaller screen than auto GPS units, they are durable and small enough to carry with you right in the palm of your hand, making them ideal for camping and hiking. Besides the auto and handheld GPS Magellan systems, there are four other categories of GPS instruments: Marine, PDA, laptop, and aviation. Coming in all different shapes, sizes, colors, textures, and purposes, Magellan makes a device that is perfect for everybody. The auto GPS devices can plot directions and help you find your way around downtown Miami. Marine units alert the user to the location of buoys, lighthouses, and even fish. PDA and handheld devices are portable and can go with you just about anywhere. Laptop units are just that, GPS laptops. Aviation units are, of course, used by pilots and aviators up in the skies.


Magellan is a company that has its headquarters in Santa Clara, California, and they also have European headquarters located in France. Enjoying exceptional revenue growth during the GPS revolution, the company is known worldwide for its award-winning variety of GPS navigational systems, consistently leading the industry in directional innovations. Magellan also stakes claim to the best-selling single frequency survey product line in the world. Some of the most popular award-winning models they have made are the Magellan Triton, the eXplorist, the Maestro, the Roadmate, and the NeverLost.

GPS Overload – How to Choose the Perfect Device for Your Needs

Buying a Global Positioning System (GPS) to meet your needs may not be as simple as one might think. There are a myriad of different devices, for many different purposes.


The first thing to consider when buying a GPS device is its primary use. Will you be using it on the road, on the trail, or on the water?


On the road devices are usually temporary mounted in the vehicle with suction cups or bean bags. Most of these devices have turn-by-turn instructions and auto correction if you miss a turn.


We recommend getting a device with the auto-correction feature, that way you don’t have to mess with the device if you take a wrong turn, it will recalculate the route for you automatically.


There are some devices that are also portable, so you can unplug them from your vehicle and take them with you as you walk around in a large city.


My favorite in this category is the Garmin c330, c340, and c530 series. They are a wonderful size for using it in the vehicle and small enough to use as a portable. They have city maps pre-loaded, so they are not much use off-road.


Many of the newest designs have built in picture viewers, MP3 players, traffic updates (careful, that usually costs extra!!), and many other bells and whistles.


One of the best features of the Garmin c-series line is the ability to ask for the closest landmarks, such as food, gas, shopping, golf courses, etc.


Like anything you buy, make sure you understand what the device has and what you want to use for before making the final decision!


One of the most asked questions is should I buy the car with GPS already in it?


Personally, I don’t like that option because it limits how you can upgrade, and the device cannot be used in multiple vehicles.


In addition, some car manufacturers are charging several hundred dollars to update the map data on these devices and you have little choice in using them to do this.


The GPS market is an ever changing market and I like to be in control of which device I want to purchase.


Having said that, I am choosing to have a device mounted to my dash or windshield (suction cups….also illegal in some states, so make sure you know which ones!!!) with wires trailing to the power source.


On the trail devices are handhelds which depict topographical, or basic mapping data, not detailed street level details. These are great for hiking and geocaching. They have the ability to either import or download coordinates of a location (called waypoints) and then tell you how close you are to that waypoint.


Ever fear of getting lost hiking, well, you can set different points as you walk, like a breadcrumb trail so you can get yourself out the way you came in. These devices range from -0+ depending on the different capabilities of the device.


Higher end models allow you to buy pre-loaded map detail on memory cards, so they can double as driving directions, however, they still don’t have the turn-by-turn capabilities.


GPS devices used on the water are fixed mount devices. These devices can have water depth, temperature, etc, especially helpful for the fisherman.


Maps that can be downloaded can have tidal waters, known shipwrecks, ports, and are very detailed. There is a huge range of devices to consider in this area.


Keep in mind that mapping software used on these devices changes about 1-2 times per year. Less frequently for the maps on the water.


Understand what your devices downloading capabilities are so you don’t get stuck with outdated maps forever!


Be aware that maps change, you have to be somewhat flexible when following the directions. I have had instances where it tells you to “turn left here”, only to have that be the wrong way on a one-way street!!!


In other words, these are guides to get you close to where you need to be, you cannot use them as gospel….common sense should prevail!

Is a Gps Useful On Vacation?

Vacations are times to relax and enjoy, not worry about finding your way around. Are you flying, or driving? Are you going somewhere that you know well or somewhere totally new? Are you renting a car if you’re flying, or are you going to depend on taxis? If you are traveling by taxi do you know if a ‘shortcut’ the taxi driver suggests is really a shortcut or possibly are you being scammed to increase your rate. What are your plans once you get to your destination? Are you going backpacking, hunting, or fishing, or do planning a trip to a resort and plan on lying by the pool and just relaxing? Wouldn’t it be nice not the have to worry about finding a location, or a good restaurant. Your visit would be much more enjoyable without this concern.


Is it possible that you will be off in your own airplane, with a GPS you can create your flight plans and get automatic calculations of headings, winds, time, and fuel or recalculate your heading. Are you driving or plan on renting a car once you get to your destination? Do you know the route well or is this a new adventure? Whether this is a trip that you frequently make or not a GPS can be indispensable. What if you get detoured due to an accident or road construction, what if you run into a large traffic jam do you need to sit and wait, or is there possibly another route you could take? Have you ever wanted to get off the beaten path and explore somewhere new but were afraid of getting lost? Wouldn’t it be nice just to take off to somewhere new without the fear of getting lost? Do you plan on going fishing? Wouldn’t it be nice to know where the fish are, so you can spend your time catching fish, instead of spending your whole vacation with the possibility of catching nothing?


Have you planned a trip to visit a foreign country but were afraid you have trouble getting around when street signs are in a different language? With a GPS you put in your destination and find the location that you would like to go to. There is also translation software which can be downloaded to your PCA.


Are you going backpacking, hiking or camping, or even plan on taking a bike ride, with a GPS you have the added security of knowing if you get lost you can find your way out. Is there an area you always wanted to explore, but was afraid of not finding your way back.


Vacations are too far apart (2-3 weeks a year?) and are planned, paid for and anxiously awaited for to have to worry about getting lost. Whether you plan on lying by the beach or pool all day, you might want to find a certain restaurant or shop, or hiking through the forest a GPS can take the worry out of traveling and allow you to enjoy your trip.

GPS Technology and Child Safety

What parent has had that moment of fright when the child who was just at your side is gone? Usually the child has seen something of interest and just gone to investigate, or has gotten separated in a crowd, such as being at a carnival, and although it may only two seconds to locate your child, it feels like two years and when you do find them your heart is racing, your hands are shaking and you don’t know whether to hug them or scold them.


The possibility of someone taking our child is a real fear every parent carries with them. Just pick up a newspaper or watch the evening news and reports of children being kidnapped or abducted are constant and the heartbreak of the parents is just so overwhelming. Now what if there was a technology that could find that child instantly?


GPS technology is now being used to help keep track of children and allow parents to know where their child is at all times. These devices are usually small enough to fit anywhere-backpack, pants or coat pocket, etc. and lightweight enough not to be burdensome. Some of these have pre-programmable buttons so the child can keep in touch with their parents or call for help if necessary.


These devices range from tracking devices that will beep until the child is found, to cell phones with GPS technology installed, to watches that if forcibly removed will automatically activate. There are even backpacks available with GPS technology installed. Some of these will activate if the child is too far away from the parent. And there is even one that is implanted in a shoe.


Of course the main problems with these are the child is going to lose them, or if the child is abducted they can easily be disposed of. I can envision the day when it will be possible to have a GPS transmitter implanted in a child via an injection or some other simple manner.


There are other concerns also. Are only children with parents who can afford this technology are going to benefit. Is this going to increase the number of lower class children, whose parents can’t afford this new technology, being abducted? Will someone, such as a child molester or kidnapper, find a way to use a child’s transmitter signal to locate the child? Also how are our children to adjust to the fact that they are constantly being monitored?


How secure are our children going to feel knowing that the world is so dangerous that their parents need to know where they are at all times? Are we stripping a part of their childhood away from them? Who doesn’t remember, as a kid, going somewhere you knew your parents didn’t want you to go, but as children we are adventurers, and if we got into trouble or got ‘caught’ being where we shouldn’t be, we more than likely not only got punished but also learned a lesson. We grow and mature by making mistakes and learning from them, are we going to take part of this education away from our children? At what age do we stop? Do we continue to monitor them through their teen-age years? A time that can be the hardest time of any child’s or parents life, it’s a time where a teenager needs to mature and a parent needs to learn to ‘let go’ and allow the child to learn on their own-mistakes and all.


Although this technology has some very great qualities in the protection of our children, the possibility of abusing this technology must also be addressed. We all want our children to be safe, yet at the same time they must be allowed to grow to become functional adults.

What is GPS and How Can It Be Used?

GPS stands for Global Positioning System and was initially designed to be used by the U.S. military and is operated by the U.S. Defense Department. This system consists of 24 satellites, these satellites are 12,000 miles above us, are constantly moving in a precise orbit, have an atomic clock, and are solar powered. They do have a battery backup so they will continue to run in the event of a solar eclipse, and each satellites has a small rocket booster to maintain their orbit. The first satellite was launched in 1978 and it wasn’t until 1994 when there were a total of 24 satellites. Each satellite has a life expectancy of about 10 years, so new satellites are constantly being built and launched. Each satellite weighs about 2,000 pounds and is approximately 17 feet in width when the solar panels are extended. In the 1980s the GPS became available to the public, and although it is still maintain by the U.S. Defense Department there is no charge for its usage by the public.


These 24 satellites orbit the earth twice a day and continuously sends the location of the satellite. A GPS system can tell how far a satellite is away by comparing the time difference between the time a signal was transmitted and the time it was received, the longer it takes the signal to be received by a receiver, the farther away the satellite is. If a GPS is receiving signals from three satellites it can calculate latitude and longitude. Altitude can be determined if the GPS is receiving signals from four satellites.


GPS can be used for navigating your car through traffic day-to-day or tracking a fleet of vehicles. Not only can a driver use a GPS for directions the main office knows where that vehicle is and the speed of the vehicle. GPS can be used while on vacation for activities such as hiking, camping, or hunting. Is your passion fishing but get frustrated trying to find the fish? With a fish finder which uses both GPS technology and sonar you’ll know exactly where to go to find those fish. GPS technology is also being used as a way to track your pet if he wanders off or to safeguard a pet from being stolen.


Another use for GPS is as a child finder with a receiver in a child’s cell phone or wristwatch to ensure a child’s safety. It can be used in a teenager’s car in order to both know where they and how fast they are driving. This could also be used to keep track of someone who tends to ‘roam’ but is not capable enough to find there way back; i.e. someone with Alzheimer’s disease.


As GPS technology improves, it uses will increase. Who knows where it will take us next?

GPS Technology and Mobile Phones

Imagine driving somewhere new, you’re lost, unsure of where you are at, and the more you try to find your way out the more confused you get. Do you know how safe the area which you’re in is, is it safe to get out of your car to ask for directions or are you risking being attacked? What if you are threatened or attacked, you have your cell phone, dial 9-1-1, but are unable to tell the operator how to find you. Imagine having an accident, or witnessing an accident, but you are unsure where you are, you call 9-1-1 but are unable to tell them where you are. Imagine becoming ill while in your car, you dial 9-1-1, but become unconscious before you can tell someone where you’re at, how will anyone find you? Imagine being on a hike or bike ride when you suddenly realize you do not know where you are, how will you find your way back safely?


The U.S. FCC (Federal Communications Commission) has mandated the E911 (Enhanced 911) which requires that the location of any cell phone used to call 9-1-1 can be determined. This program is divided into two parts; the first requires carriers to report the telephone number of the caller and the location of the antenna that received the call. The second part requires carriers to be able to provide a more precise location. This will require that the manufacturers to install a GPS receiver in all cell phones. The benefit of this not only means that a cell phone can be quickly located, but that cell phones will have the ability to receive driving directions, and to be used as a hand-held GPS out of the car.


There are two ways that a GPS cell phone can be used to get driving directions. The first is to subscribe to a GPS navigation service, which is becoming available but is limited at this time. The second way is through use of a software program. Being able to subscribe to a navigation service has its disadvantages, if you are outside your coverage area your navigation functions won’t work. Plus, not only do you have to purchase a GPS cell phone, you must also pay a set up fee and a monthly fee and be under a 3 month to one year contract.


The second way to get driving directions is to buy a software program, but you need to have a compatible cell phone. The programs and maps are on a memory card and there is no need to pay a monthly fee and since the maps are in the phone you are not dependent on a GPRS connection.


If you want to take your GPS cell phone with you while out of your car, not only are there integrated GPS cell phones, there are GPS add-ons available also.


Another advantage to having a cell phone with GPS technology is that parents know where their children are at any time (as long as they have the phone with them). Some carriers are offering this child location service as a ‘peace of mind’ feature. There is usually a monthly service charge for this service.
