Step 1
Take your budget into account. If you're lusting after a high-end GPS system for your car, buy a built-in unit from your car dealer. If cash outlay is a concern, good-quality dash-mount and handheld systems are one-tenth to one-fifth the price of built-in ones.

Step 2
Imagine where you want to use your navigation system--driving around city streets, hiking mountains or touring the Virgin Islands in your yacht? Each intended use has its unique needs, whether it's street maps and directions, topographical and altitude information or extra battery power.
-
Step 3
Decide what kind of maps you'll need: general, what-state-am- I-in maps, or precise city-driving directions? This will determine the capabilities you'll need from your system. After you make your purchase, make sure all the appropriate maps are loaded.

Step 4
Look for features such as audible alerts that warn you of upcoming intersections or turns, and scrolling maps to track your progress. Opt for units with a larger display to avoid zooming in and out repeatedly to read names and find intersections.

on 12/15/2008 Of course, good navigation must comes with good GPS map. Igo Route66 TomTom map are good, but you need to buy the copyrighted map which can be upgraded. I highly recommend autodvdgps.com, which selling good navigation and good map.

on 11/22/2005 Honda, U.K. informed me that the Satellite Navigation system installed in my CRV is not fully mapped for France. I was told this fact, after I had bought my CRV. They are quite right. Their current DVD is about two years out of date.
