Default Garmin GPSMAP640

Looks like a nice unit for backup on the boat (or primary for small boat) and for the car

5.2" WVGA Touch Screen

Marine - Preloaded G2 Charting, XM Weather (with opt antenna & subscription)

Auto - Preloaded CityNavigator Charting, Voice Navigation, XM Traffic (with opt antenna & subscription)

Appears that the GPS antenna is built-in
