If you have OnStar and the airbags deploy, a signal is automatically sent to OnStar. OnStar will automatically attempt to contact you in the vehicle (the vehicle actually has a cell phone with a number in it). If there is no response or you tell them you're injured, they will automatically send emergency vehicles to your location, and believe me, they can almost tell what side if the street you're sitting on. Anyway, the communications portion of OnStar works through the stereo. I doubt (but can't swear to) that disabling a radio will prevent your airbags from deploying. At worse, it would only prevent communication with OnStar.
