Question about Pioneer DEH-P4100
I have a Pioneer factory head unit in my '05 Scion xB. The "volume down" button stopped working out of the blue. Nothing has been spilled on it, all other buttons work. Any ideas?
I had a similar problem with one of the cursor type keys - I ended up taking the face apart (4 small screws on the back then gently prise apart) & discovered the small pin attached to the back of the button which presses the internal switch had slipped off the pad, it took a couple off attempts to put it back together again but once it was re-assembled it was fine, just be careful not to lose anything! ;)

Listen for click sound , the volume up will have it , if the vol down does not then you have a faulty button (internal tactile switch) which needs to be replaced. If you can hear the click then there is a communiction error between then button and the microprocessor which also needs to be taken in for a checkup.
