i just installed my avic 700bt in my audi s4. so far it works great for the most part, but after about ten minutes the touchscreen stops noticing me hitting anything on it. the touchscreen works great at first, then it slowly starts not noticing me touching it, then just stops noticing anything. buttons still work on the side, and still plays music, just looses touchscreen. ??? it has the bypass installed and is on 2.0 software. any ideas?

Try resetting the unit - I think sometimes (apparently wiht my unit I have) it does not reset properly at the end of the software change. Once I reset mine a couple of times, the gemlins seemed to disapear.

hope it helps!
