Hey I have a 2002 chev RCSB, and I was wondering if anyone ever put a 03 or newer gauge cluster, radio and HVAC controls? I seen the threads about putting a double din in an 02 but I'm more curious about converting everthing too. Plus I seen theres a 140MPH factory gauge for the 03 and newers. A kid at a bestbuy told me the radio wouldnt work because of the switch voltage is from 12 on an 02 to 5v on a 03.

Thanks
Eric
