I have recently had to replace a Sony CDX-L410 in my Rover 25 when the CD player mechanics broke. The Rover has a couple of small paddles on the steering wheel which adjusted volume, changed tracks or radio stations, fast forwarded etc. I have purchased a used CDX-GT530UI which I have installed and which works fine, including with the IR remote, except the steering wheel remote does not operate the unit but does prevent the unit's volume control and track changer from working.Unplug the remote jack from the back and control is restored. The installation instructions for both units imply that the Rotary Commander RM X4S would normally be used as the remote control which is why I thought the Rover controls would work. Any suggestions would be much appreciated.
