I’ve always wondered how accurate auto navigation systems like GPS really are. They’ve always seemed a little extravagant to me, and the thought of driving around with a computerized voice telling me how to get somewhere seemed a little too futuristic to be true. But that changed when I was on vacation recently and had the opportunity to use a rental car equipped with one of the new auto navigation systems.
I was in Florida where it can be impossible to find your way around, especially in the packed tourist cities like Orlando. We were staying on Disney property so my brother could attend a conference, so my days were free to explore the area. Being by myself, I didn’t want to get lost, so I figured it would be as good a time as any to do some research on auto navigation systems. I rented an Explorer with a GPS unit installed in the dash, and I immediately began to test it. I wanted to see if it could accurately lead me back to my hotel and to other short destinations that I already had the directions for.
Another feature to keep in mind when comparing GPS devices is the precision of the directions they offer. Roads change all the time, new roads are built, and construction is a huge issue. You want a system that will keep up with changes on a regular basis, and can do so with little work on your part. Updates may come regularly, or you may have to request one before you start your trip. You can find car navigation systems online, and at specialty stores. Shop around for the best price and ask a lot of questions before you buy. Find out if there is a monthly or yearly fee for service, and what extras a particular model may offer you. Find out if the directions are easy to access, if the model offers voice directions, or if you have to read the screen. If the screen is too bright, or if it is affected by sunlight, you aren’t going to find it easy to use in most cases.
Good auto navigation systems are like mapquest. Ninety percent of the time handheld GPS are accurate, but they won’t always give you the best way to get somewhere or provide you with up-to-the-minute information about road detours and other changes along the route. I imagine the technology in auto navigation systems will only continue to improve, and the next generation may be able to sense when you’re about to screw up and make a mistake and will help you try to avoid it. Until then it makes sense to get directions from a real person who knows the area as well. Just to be safe.
