I have a 1997 E-320 with the AM/FM cassette player and the 6 CD changer in the trunk. AM doesn't work too well and I don't like having to go into the trunk all the time to change CDs. Is there any CD player that will fit right into the AM/FM radio slot so I can change 1 CD whenever I want but still be able to use the 6 CD changer?

Thanks,
DJ
