			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
