Hey guys.. I have a problem with my Pioneer DEH-P550MP cd player that I hope you can help me with. The cd player will not turn on when wired up, unless I wire the yellow igniton wire and the red power wire together in the same connection. However, this causes the cd player to have no memory and I must reset everything every time I turn off the car. Anyone know why this might be?? It's really annoying having to reset all settings four or five times a day.
