Don't even think about any gps but Garmin. Been there, done that. I've used three different brands and Garmin units are miles ahead of all the rest. Wish my Lexus SC 430 had Garmin instead of the Pioneer unit. I had a Garmin Street Pilot on my first Honda Goldwing. Got stolen at a motel, but worked great.
