I think that the nexus 7 will be a good option for this. I have already seen pics of different mounts for it in vehicles. If you could port the feed, possibly through BT or something, to your in-dash unit that would be cool, !

 

Let us know when you get your nexus and start your in dash install, I'd love to get tips and advice as I would like to do the same thing (possibly with as little fabrication as possible)

 

I too would like to see a all in one indash log-nav setup. But for now its just the greddy informeter touch and tom tom.lol Want to trade your stock mitsu navi for stock 6 disk and cash?lol

 

avic systems use windows ce..so its possible to use evoscan, also its fully "hackable" so you can launch windows ce instead with a seperate gps/music program also..check out avic411
