bio ^ thats a great idea, someone on the forums is doing the same and it looks great so far.

 

That would be pretty cool lol i dont have one though. I was thinking maybe a GPS?

 

I would do an Ipad or comparable tablet. You could make a nicely finished holder/bracket for the tablet that would both charge the unit as well as maybe an OBD2 dongle for car diagnostics Would also be nice to have it patched into the car audio for streaming or downloaded movies/music ect.
