aftermarket head unit
I have an 03 530i and want to have an aftermarket deck installed. I went to a shop and was told it would be $50-$150 for the install depending on whether or not they had to go behind the amplifier to put the new one in. They were not sure if that year had the amp behind the factory stereo as most Mercedes and newer BMW's require this and would like to know before I put my car in. Any info would be appreciated.
