Go with Pac. They are pricey for a reason, they are a superior product.

Yea id agree...although mine hasn't arrived lol...he's just gotta firgure out the correct model

PAC OS-3 non-bose is the one i need. i beleive.

I just checked the pac website and that is only for 07-08 silverado ...but it may work but according to their application chart the one a linked earlier is the one you need ..os-4... I think

07 08 09 10 are all the same truck.

06 was different and early 07 gm calls 'classic'

I think the os3 would work but there is too many variations. the os4 work for anything 07+
