For the last several days I have been doing a lot of reading and research on the radio for my 2000 E430. I discovered a place in Saddle Brook, NJ. called BeckerAudio which specializes in Becker Radios, a main stay of Mercedes. They might be able to recommend a radio that fits your criteria. Better to hear it from people that do this all day, than some high school junior that works at a big box, and knows nothing except where the cash register is.
