If there is one thing in driving that is certain, it's the fact that if you have a GPS system with you, driving becomes a lot less stressful. By the time you are done reading this article, you will know what the most important parts of a GPS system are so you can purchase one that is right for you.
Display
The size of the screen can be a big factor when it comes to GPS systems. The smaller the screen is the harder it will be to see where you will be needing to turn. It is best to get a screen between 6 and 7 inches.
Maps
After you find a system that has the screen size you like, you need to take a look at its map coverage. It is very important that you find one that covers all of North America (if that is where you are from). The majority of them will cover North America by default. Some of the systems out there allow you to plug a GPS into your computer on download maps onto it.
Directional
Having your GPS system actually talk to you is probably the best way to get directions, it sure beats having to constantly look at the map. Almost all systems have a built speech, but some of the more pricey systems have built in text to speech. This allows you to hear the actual street names instead of hearing "turn right in three miles" In our opinion, this function is easily worth the extra money.
Design
You need to choose a design that you like, there is no right or wrong for this. However, if you drive more than one car it is important you look for one that will allow you to transport it easily from car to car.
