It's Tab 4. Not the ideal, since it does not do USB hosting
could not get my hands on this project due to lot of work. But getting back to this and hopefully will have updates. I'll post pics if any progress...
Thanks for great & valuable comments.

If your tablet supports fast charge, you just need a fast charge adapter, it'll definitely charge while on if it supports that.
For overheating, you could put a 12v PC fan on the back, and if that's not enough, make a port in the climate control ducts pointed in its direction. Under auto, the center vents only blow air when they're blowing A/C anyway, so heating should only be going to the floor and defroster.
Super cold, well, you'll just have to wait for the interior to warm up.
You shouldn't have a problem doing the navig screen lifting - a micro-roller switch placed in the right spot should be an easy way to toggle active when it's up all the way.
The little buttons are just a bunch of delicate soldering.
Good luck and post up some pictures!
