It was working on the Base Radio. I have a Bluetooth Adapter that plugs into the AUX port, so it's not that big of a deal, but just wanted to keep everything OEM working.You don't mention it ....but did you try the bluetooth prior to installing the radio? It should be pretty easy to put a meter on the wires coming from the steering wheel switch and see if it is working. I guess what I'm wondering is 'was the radio on Ebay because the bluetooth module wasn't working'.
Hope you get it working. Might not be for you but bluetooth is 'to me' the best part of the whole system.
Since the original was only 16-pins and the new one is a 32-pin connector. Was there something that needed to be spliced differently? This post mentions a different module needs to be purchased, but doesn't say which one.
