Does anyone know if the mounting brackets are different on the 2005 and 2007 Audiophiles? I am looking at upgrading my 05 but the picture I see of it does not show the brackets clearly...they do seem like they are in the same location but somehow look slightly different...I have been told that the antennas are different but I know how to fix that...I already have the sub and harness, just don't have the right head unit...Anybody have a head unit that will definitely fit???
