i installed my d3 in my 2004 f150 back in april, i use the ipod cable and sirius sat radio. as of a couple weeks ago my touch screen will stop working. my music will continue to play and i can change songs or stations with the hard buttons on the side. then 20 minutes later it'll work for a couple presses then it'll stop working again. i've tried reseting it and no luck. has anyone else heard of this?

I have the exact same problem I also tried resetting and the problem came back the next time I started my car.
