What about this..

Why not this one...its good enough for running the Baja 1000 can we say bulit proof GPS just a little larger but the depth...4" now that might be a problem. Mount..custom would be needed.

Good thing is it could be used for any off road use you may need a gps for...4x4's quads etc.

Custom mount, hell! Turn that bracket up and screw it to the windshield!

Yes, but it only gives you charts for being "off road" so it be useless for those of us that ride our bike on the road.
