So my last motorcycle GPS was a Garmin 60csx which I still use, but wanted something newer, and mostly street ride now, so decided take chance with the Garmin 396 with not much research on it.. other then good reviews.. Just ordered today but curious how it hooks to bike? I'm assuming there some sorta cradle it mounts to that might have power all the time, that goes to battery, but I want to use on variety of bikes, so want way to go back and forth, is it just USB charged? if so I can run thru 12 volt cigarette lighter ? don't have one mounted on bike yet, but want to order it today if that's way I need to mount so have everthing ready next weekend.. Does it come with maps you can install on you computer as well? I know its preloaded? but I like be able look at maps routes on computer, are u able to upload tracks, waypoints, gps stuff,etc similar to the 60csx? just asking cuz maps preloaded, and I'm assuming it doesn't come with a DISC to install em on computer.. to do that , u have to buy city navigator? or does it come with a license # you can use to download maps? thanks guys.
