Installation materials for CD changer in 1991-1993 W124 class sedans or coupes. Some or all parts may work in W126 or W140 sedans but I cannot vouch for that. I have the mounting bracket, cable set to connect CD changer to the radio chassis, carpet-type cover for the unit, and a set of installation instructions. These items are enough to install a Becker changer. The cable (retail price about $100 3 years ago) is also part of what is needed for the Alpine changer, but an additional interface cable is needed for the Alpine. The bracket is actually a W140 bracket, modified for use in a W124, so it could dbe modifed again for use in a W140 and possibly in W126. (Bracket is only for Becker, Alpine uses a different bracket.) Price: Entire set $75.00 plus shipping. These items were used for about 2 years, car sold, CD changer sold separately.
