Is it possible to upgrade an 03 GMC Sierra to include the steering wheel controls?[radio and functions] What is involved? Any help is greatly appreciated.
Thanks

Since the radio controls were available on the 03, it is possible..You will need a different wheel and SIR coil for sure.....After doing so, you'll need to re-flash the bcm too.....A guy I know is in the process of doing this right now....I'll let you know if there's other things that need to be done...

Thanks Parts Guy...I appreciate it.
