Does anyone know if you can put a 2004 headunit that is Sirius ready into a 2003? I have a 2003 Cobra and want to get Sirius in it, and would love to have the factory integrated headunit if I could.
Yes it is possible to do. I had to buy a sirius ready deck and found one that was a factory 6-disc mp3 player which is sweet....
I also had to purchase a new harness that converted the old style plugs into the new one... it was pricey but I was anal about it and wanted the factory setup. Its a convertible and didn't want to have to take the sirius external unit off everytime I parked with the top down.
I then bought the sirius ford unit and plugged everything up and bingo.. works like a charm.
