My touchscreen blacks out and comes back on when it wants to. The stereo keeps playing but you cannot use the touchscreen when it blacks out or the other buttons. Buttons on the steering wheel do work however. Audio also pops a little bit when touchscreen comes back to life. Anyone else have this problem? could it be as simple as a loose wire on the harness? How do you get the trim off to pull out the head unit? Thanks in advance.

Sounds like it may be the power supply for the lcd backlight. Internal, so you won't be able to do anything with it except pull it out and send it in for repair.
