i want ot install a new HD radio receiver in my 2003 Silverado SS. Crutchfield says they have an interface that will allow all my onstar functions to operate but i dont think i can trust them.
Does anyone have any experience installing onstar compatible equipment?

Crutchfield is a very reliable website. If you doubt that a product isn't On-star compatible, you can probably call them and they will more than likely answer any questions you may have.
