When buying a GPS device to the car, look for touch-screen navigation, voice prompts for directions and a travel computer. They will help you keep your eyes on the road and the trip computer will tell you how much you need when driving from point A to point B.

* Data storage: Many GPS devices come with built-in maps, but you can store even more information if your device supports Secure Digital memory cards or CompactFlash. Mapping data not occupy much space and many units even come with a 128MB card.
* Combination GPS units: Standalone GPS devices work great for most people, but some personal digital assistants (PDAs) and two-way radios come with built-in functionality. If you need a PDA or a two-way radio, consider one of these hybrids.
* Weather resistance: as with all electronics, you will need to keep your GPS device water and try not to drop it. Look for a GPS device with a rugged design and weather resistant features if thinking to use it outdoors.
