So here is my question I have an 09 Silverado with blue tooth what my goal is, is to change the VCIM to one that will now give me the option for the onstar remote link app to work as well as continue to use onstar and blue tooth my current VCIM is a 20783877 it is the one that has the three antenna connectors on it. I also have one that came from a 2013 Silverado it is part # 22898335 but it only has one antenna connector on it..Any help you can provide I would be greatful for, Thanks
