The Becker 1480 was not CD ready and I don't want to put another unit in the dash other than a MB unit because I don't want to modify the looks. As far as I know the only way to install a CD player would be to add an aftermarket stereo and/or CD changer in the trunk - which I want to avoid - unless someone knows of another way to use my factory radio and add a CD changer? I don't know if there are MB CD units that are compatible with my Becker 1480.
