You can also easily transfer MetroGuide data from a personal computer to the StreetPilot GPS, StreetPilot ColorMap, GPSMAP 295, and eMap units by inserting the blank 16 MB data cartridge. Just select a desired location and download the data. You'll see details such as the locations of restaurants, banks, gas stations, tourist attractions, and more. And you can use your GPS to look up street addresses and points of interest, then navigate to them with the help of onscreen arrows and street-level detail. The package includes a blank 16 MB data card.

Rating : - A must have
Its a must have if you are using garmin emap. Once you download the data from the cd rom into the memory cartridge you are ready to roll. Expect to see the whole area on the small screen. I would say with out the mapsource and the cartridge (which you have to have inorder to download the data) the emap is not complete. If you are willing to invest the money then i would suggest to get either the 16 mb or much better the 32 mb cartridge.
