My 1990 300E currently has some aftermarket head unit installed with CD player. I appreciate the CD player but don't like the appearance of aftermarket stereos. I want a genuine MB stereo with an integrated CD player but none of the W124s ever came with such a thing. I was wondering if it is possible to install a W210 stereo perhaps? If not I guess I will just find a good quality original Becker and install that assuming the installation of the aftermarket stereo won't make reinstallation of the original unit a headache.
