Hi all, Just got an 05 pkg6 and the guy had heated leather put in at the dealership so its is one loaded vehicle. 16k on the od too! I ordered the sharkfin and am trying to figure out the siurus sat hook up. I want the functionality and I am gathering the latest sirius radio has everything but being able to scan from the steeering wheel. guse at the price i can live with that. Anyone know what the backup cam cost to retro?
