After lots of hit and miss internet research, I decided to get a Zumo 450 GPS for my WR. Costco had it for $349 with a bracket, street map and cable, so I went for it. The Zumo 450 is aimed at street riders, but from what I can tell will be able to do the relatively simple off-road stuff I need with the correct additional map installed. It lacks some functionality that the serious off-road units offer, but I think I will prefer the larger screen on the Zumo. And I'll be using it mainly on the street anyway. It seems like people are super loyal to the GPS units they choose, so as a newbie to GPS, I don't claim to be an expert. The Zumo comes with a universal mount that swivels every which way, but I wanted something cleaner that would put it more out of the way of damage for off roading. So I made a little aluminum plate that bolts to the top of my ProTaper bar clamps. The Zumo mount is screwed to the plate. The zumo mount has a quick release so you can take the GPS with you when you park. The set up came out pretty well, and so far I'm really happy with the GPS unit.
