I drive a 2001 Mercedes C 240. I have the factory radio that comes with it but I use a cassette tape to hook up my music too. I also have the CD changer but it doesn't work at all. Recently the tapes that I have been buying have been getting stuck in the radio and right now I am at the point where I want to buy a new radio or go on eBay and find another factory radio just like the original. Any advice???
