I have a 2008 Lincoln Town Car that came factory with the Soundmark 6CD changer. The CD changer was giving me errors and jamming and I noticed that a new 6CD replacement was sold out. I went ahead and ordered this CD/Cassette Soundmark and the plugs fit perfectly and works great. 1:1 fit. So if anyone has the same issue (or you want to upgrade from the cassette to the 6CD), no modifications necessary. Both of these Soundmark radios are interchangeable.
