Have just installed a new Pioneer DEH-P77MP, very nice it is too...
I got the steering wheel control interface with it (PI 806).
Anyway, the following things have happened.
1) No lights on the Steering wheel buttons
2) The track up and down wheel buttons both go "down" (suspect this is just one of those things with interfaces).
3) Most importantly, the unit doesn't retain settings when the ignition key is removed. Is it to do with on of the wires in the connector not being right? I have to keep resetting the presets!!!
Any help much appreciated
