I used the 3.0 update on this site last july and it's worked great until yesterday I used my steering wheel controls while listening to XM and the unit went into a loop as if the previous preset button was being held down. I then discovered the knob on the unit causes the same problem. When I adjust volume, the volume adjust as suppose to but it keeps getting the previous preset input and the touch screen doesn't respond but the hard keys still work.

I've gone through the 3.0 update but that doesn't fix the problem. Any thoughts?

Fixed it. The Pac steeringwheel adapter burnt out and by leaving it plugged in to the back of the f700 (with it's harness unplugged) caused the issue. I just unplugged the broken SWI-PS and it works like normal now.
