I put a REN radio replacing my plain RES with sat. Anyway with it I decided at the time to ad the Uconnect from the dealer, now I have to go in and get the unconnect starscanned in anyway that is not my question,On the back of the radio there are three sections to plug power speakers whatever in not including antenna and sat nor Nav. just the grey section. anyway when installing the unconnect the instructions say to take out the (if you are looking at the back) connector and plug in the unconnect one then plug the factory one into it, okay no problem, the it says take out the small center one if there which it was and has more wires than the one that the Uconnect calls the mic connection, anyway you replace that spot with the one from the u connect harness then leave that disconnected. The funny thing is so far everything works, except the uconnect, but I am wondering what all the other wires were for? Anybody? I know RT has to know this one he seems to have all the connections!!! Please somebody tell be what those wires did before
