Has anyone had an issue with the buttons on the faceplate becoming unresponsive? I have an 8600 and on the ride home last night I tapped the home button and got no response, all other buttons other than volume up and home work just fine. Tried reset but did nothing.

Bad touch panel. Easy replacement 

Touch panel for the hard buttons right, the screen is fine  just a couple buttons on the bottom.

Pioneer is aware of these problems, but they are wanting us customers only to send units in and charge for 4 weeks

. F..K You Pioneer post the fix !!!
