MD or CA?I live in Pasadena. I have a 2006 GMC Sierra 3500 4x4 Dually on order and am trying to get every thing ready for when it gets here. I like to do things all at once instead of waiting. Thanks for the offer and I will keep it in mind. The dealer told me today that it would be here by the end of February some time.
You will need a Head Unit C2 plug then... I ordered mine without Onstar and XM too. Without these accesories (auxilary inputs), there was no need for the factory to install the C2 harness.I live in CA. I ordered the truck with the Bose system. It was ordered with all of the options except onstar and xm radio.
Do you have the part number for the harness/plug?My truck was ordered w/o XM and OnStar also.....I got the C2 plug from Specmo......just ask the service rep for the wiring harness kit for the factory radio.
