Alpine 6 Disc Compact Disc Changer CHM-S620. Works with the factory radio. Came out of my 1995 E320, but should probably work in other cars (both Mercedes, and maybe other cars. It worked with the factory head unit in both my M3 and 911). Comes with an extra CD cartridge. I recently bought a in dash CD player, so I no longer need my CD changer. Asking $200.
