Hi All,

This is a strange one. The remote control buttons on the steering wheel only work when the engine is not running. The ignition can be on either accessories or in the on position (dash lights on) but as soon as you start the engine, the buttons stop working. I have checked every function on the radio and CD and all works fine. This problem has only just started and there was no indication of a problem developing such as the buttons working intermittently, everything worked fine until one day it didn't.

Yes I have checked the plug on the back of the radio, no wires are broken, and they are getting resistance readings from the steering wheel buttons. I have tried swearing profusely at the radio and steering wheel but to no effect

Any ideas?

This is the basic unit, not the 6 stack.
