Pioneer DEH-P6700MP - Only CD and volume work. Any ideas?

[christophercale]

Hi Everybody -

After searching for hours on the net, I can see that other people have had this problem, but I find no solution. I have a Pioneer DEH-P6700MP head unit and only the CD player and volume control are operational.

Is this thing simply locked (or something), or has it seen better days? The unit is about 5 years old.

I saw one case where a guy said that pressing the "mode" and the number 1 button on the faceplace at the same time cleared the problem, but that has not worked for me.

I tried disconnecting the battery, which cleared everything on the unit. However, now I'm stuck with that stupid flashing reversing display, and I still only have CD and volume.

Any ideas? TIA,

Christopher
