if you taken your car to get serviced at an mb dealer... the Radio Code (R/C) is usually writen on the invoice as part of your vehical description......
well... atleast both dealerships out here in kc have it on them...
i have an extra radio i woud sell you for cheap for parts if you want one.... it came from my 94 e320...
50 bucks including shipping? you will have to replace some of the buttons off of yours and put them on this one...
the radio worked fine but has been sitting in my garage from like 3-4 years.. changed it because i installed an audio 10 (cd instead of cassette)
email me for pictures
