Thanks for your feedback, really appreciated.
Diagnostic - Unable to try, because screen is Totally blank/dark, nothing shows. ONLY time screen comes up when I put the car in reverse, backup camera Feed works. That is all.
BANG - I did bang the top/dashboard, but did not change anything.
Wires REseat - I tried to unplug/replug the wires to the screen, BUT since could not find any pictures/screen/instructions on how to do it, I stopped after taking the CD player out. Are there any instruction with pictures?
Someone told me there is a module, under/behind the glove box that might be bad and if replaced will need to be FLASHED by the dealer. Can anyone confirm this?
