Using a Quest2 and love it for my purposes.. Swap it between the Wing and the Triumph.. Battery powered, small enough to fit in a large cell phone case and great display (although small)... The motorcycle mount (sold seperately) is simple and bulletproof, got mine on the left grip cluster on a short RAM mount for both bikes...
The Quest2 has ALL the maps built in but if you leave them turned on, the unit takes much longer to recalc routes and find POI's.. The guy you want to post to is LVWolfman, he's the Quest guy!
