My touchscreen on my 06 TL stopped working, along with radio, voice activation, etc., about 8 months ago. I would still get the splash screen with beautiful earth pic and legal warning (then I had the battery replaced and I would get request to input security code), but the touchscreen would not register any input. The dealership looked at it and said I needed a new in trunk DVDDrive. I finally purchased one online and installed it myself today. It did not fix the problem, in fact, I believe the DVDDrive is fine because I still get the same splash screen and request to input codes, but touchscreen does not register input. What else could be the problem? Thanks

 

hello, I have the same problem with my TL 07, did you ever find out what it was? I would appreciate some kind of clue. Seriously, I am clueless.
