Yeah, I'm puzzling over the sunshade design. The fact that the bracket releases horizontally makes it a little harder to have a simple solution for quick and frequent removal of the tablet. If anyone comes up with straightforward DIY on this, please share.
I haven't received the bracket yet, but I think I've got the software and wiring figgered out. Otterbox not going to work on the new Nexus 7, so going with just www.nanostate.co
and 4 mil ziplocks when needed. Leaving on 4K+ mile trip in early Sept, much of it off road, so this should result in a good stress test.
Have been dreaming for years of kicking Garmin out of the equation...can't wait to give it a go.
