The fact that it gets power to eject/load CDs suggests that it is getting power on the yellow (battery) wire. I've tested the stereo in my other car and it is fine there. So this is why I'm asking if there's an audio wiring guide for Mercs in general, but preferably specifically for the W203. Looking forward to being part of the community.
