Hi
I have a Fiat Ducato with the standard OEM Radio fitted, and the unit will not switch off. With the ignition off the radio continues to stay on and it is not the ignition timer setting. If you hold the power off switch on for a few seconds it appears to turn off, but when you release the power button, the unit switches itself back on after a couple of seconds. Any ideas?
Cheers

Did you checked all the wiring?
