I have a 2007 Chevy Silverado 2500 HD with Nav. My truck has the steering wheel controls, however, I only have the mute button for the radio. I dont have the push to talk button. If I get a VCIM with bluetooth, will this still work with my truck through the OnStar mirror buttons? If not, does anyone know if replacing the steering wheel controls will allow this to work? Thanks for the help. Chris
