I've been tring to replace the Becker Grand Prix unit that came stock with a Sanyo FXCD500 (slot-load CD and cassette functions in a single DIN) and have had moderate success. I get sound out of both front speakers and the radio/power antenna work. I cannot figure out why I'm not feeding sound to the rear speakers. Thanks in advance for any advice!

Hi,<br> Have you removed/disabled the fader switch by your shifter? I'm not sure if your car has it; however, on my 300e (a couple years older than yours) there was/is a fader swtich by the shifter, and i had to dissable it and bypass the wires so that everything is controlled by the headunit. Here is a helpful website which has good pictures, and very informative directions and tips on this subject. <br> Good luck,<br> -Tony<br> http://www.mercedesshop.com/w124_stereo_removal.htm
