I have read through this thread as my wife is experiencing similar issues. At first I thought it was the touch screen, but now I am not sure. It initially started when she couldn't turn on her heated seats. So I started reading about it yesterday and proceeded to perform the hard resets with no success. What I saw was the right half of the screen did not seem to respond to any touches. The left half seemed to be delayed. I tried going into settings but if I hit any selection in settings, it would just carry me back to the radio screen. My wife said this morning that her phone did not connect as usual (which may be from my hard resets last night) so she hit her source button below the screen and went through all the sources. But when she got to the blue tooth, sim, line in, etc...it skipped bluetooth and just went to line in. This now has me wondering if it is in fact the module and not the touchscreen.
After work today, I had her perform the touchscreen calibration in post 5 above, and it let her do a couple of the calibrations until it got to the bottom left of the screen and it wouldn't recognize her touch any longer. Now here screen is just stuck in the calibration and white.
What do you guys think? Touch screen or module? It comes on every time and looks correct. Just cannot make selections like we normally can. Also, where is the best place to order whichever piece I need? Thanks!
