I have just acquired a 2003 Cooper S JCW with an HK system and I want to add the 6 CD changer.

Not sure where to plug the cd changer in with the HK amp intact.

Any advice would be great thanks!

 

The CD changer is meant to be installed in the boot in front of the cubby where the HK amp lives. The plug is shown here it's the black connector near the center of the amp.

 

Just plug it in...
The plug (should be shown above) is hidden passenger side boot side cover...reach around ..it is taped up...
One tip...
If the car has an AUX jack, the cable to the CD changer is unplugged in many cases..not 100% sure...but something to watch out for...
So you will have to reach behind the radio, and unplug the aux jack plug, and then plug the cable for the CD changer/satellite radio back in....
If you want both....
I seem to recall you must plug the aux jack into the "pigtail" of plugs in the boot, then run an extension cable to the front....

 

I've got both Aux-in and the CD changer, no extension cable. IIRC the pins can be swapped at the head unit.

 

Good to know!!

Great thanks so much!
