Is the CDC port accessible on the back of the head unit? I'm having a stereo jack adapter added to the changer port on Wednesday. They guy mentioned that it would probably run through the trunk. I'd rather have it come from the back of the head if possibleso the cable run is shorter. I was going to do the job myself but two sets of the removal tools run about as much as an install, so I figured I'd just let someone else do the job.
