Bought a low mileage slc 250d amg in iridium silver, 2018 model with 10700 miles, my cd player took a while to work and is still tempremental , I think the car had not been used for a while, its the audio 20 system and was wondering if I could retro fit a cd changer to the unit and could anyone give me any advice on how to get the cd working properly, cheers Paddy
