Ok I see what you are saying.. mine only plugs into the Onstar unit... I don't have the NAV radio. This still does not answer the question if this antenna can provide the necessary signal to the computer. I will see if I can come up with anything further. This is certainly interesting though. I appreciate the post... his truck has Onstar as well so does he run two antennas?
