Hi all,
I recently bought a 2000 BMW 540 and it came with a 6 CD Changer. I noticed the device was not plugged in so I pluged it in the power and coaxial cable i think. When I turned it on the audio system would not turn on. (no lights in the stereo, nothing turns on not even FM) When I take the CD Changer off it works. I have DSP, any ideas what could be the problem? Don't want to spend the 300-400 to replace the cd changer if I can get it to work.
