I have a 1993 500SEL (W140) that has a factory CD changer in the trunk. I recently bought a 1995 E300 Diesel with prewiring for a CD changer in the trunk. Since I'm planning on selling the 500SEL I'd like to change out the CD changer and install it in the E300. Is this possible? It has Mercedes-Benz on the changer and it is installed on the left side of the trunk.
