Does anyone have any information on adding a Cd changer for a 1999 C230. So far I have found out that the Cd changer goes in the trunk, is this correct. I have found the fiber optic cable and another cable , which looks like the power supply to the unit. Are there brackets that need to be installed to obviously hold the unit? And how difficult is this too do ? I've been told that all that needs to be done is to attach the 2 cables in the trunk to the Cd changer. There are various car stereo websites that offer the MB Cd changer, starting from $460.00 including the brackets up to $625.00. Does anyone know of a reputable stereo website? Any help would be greatly appreciated.
