I think I've tracked it down to one difference between the radios.

On the CDR22 Pin 6 on C1 is shown as unassigned. By following the wiring of the car, the Sound Pack amp gets its +12v from this pin.

On the BE4720 Pin 6 on C1 is the line out for the subwoofer.

So I'll need to disconnect the wire from C1 pin 6 and find a switched 12v feed for it. This must have been encountered before with Becker Traffic pro installs, does anyone have a link on here or on Renntech that might cover it?

Thanks
