I just purchased a good used and tested Mercedes Audio 30 APS and cannot locate any wiring diagrams for it by google searching. (Just lots of dubious links to download a manual)
Do any members have a diagram and don't mind sharing it please? Or have a link to a good diagram. To complicate matters I need to wire it into my W140's original Blaupunkt Amp and CD Changer But knowing what the pin outs on the head unit are would be a great start. I'll visit a local audio store to see if they can help me with getting plugs to fit which the HU which I will then solder in to the car.
