My Liberty is a 2002 which means that the 6-Disc is the type which was installed in the cargo area. However, I want to get the dealer-installed Sirius in order to keep a clean, factory look on the dash and get rid of XM because they have no good rock stations. My question is, if I remove the 6-Disc, will I have an AUX port or something like that to plug the Sirius into the back. By the way, the radio is the standard disc/tape/am/fm Chrysler radio (I don't know the model designation).
