Review eMap from GARMIN

The portable and affordable electronic map
Getting from here to there just got a whole lot easier - with eMap from GARMIN. We made eMap small enough to fit in your bag or pocket, but we maximized the display size so you can get a clear picture of where you are and where you're headed on the moving electronic map. You'll love it as a roadside companion for travelling or just getting to appointments around town. It accepts data from GARMIN MapSource'~ CD-ROMs for even greater map detail. When you download data from the GARMIN MetroGuide~ CD, you can even use eMap to look up addresses and view listings of nearest restaurants, hotels and more.
