I want to have a unit that plays satellite radio (xm/sirius), and has a hookup for ipod/iphone that charges, regular radio and possibly CD (in case it ends up deactivating the trunk cd changer). I've read of jett's setup, but that seems like you have to have to designate one of the "cds" to a separate receiver. I would just like one receiver that already encompasses the satellite. Also, if there is a single DIN that does this, it might be an easier install--so can just swap out the OEM radio head? Thanks. dvd/navi--don't really need it in my case.
