Ok, so I bought an RER MyGig head unit, great features. Sirius, GPS, and uConnect. Problem is this. I had to buy a mic ($45) and the schematics I found show a cable between the head unit and the mic. I currently can connect my phone without issue, but obviously, they cannot hear me. Does any one know of this cable? Looks to be part number 68050453AA but Dodge says no longer available and Ebay and such are asking in the neighborhood of $600 for what appears to be about a foot of wire. What the hell am I missing? Is there an adapter plug? Anyone know the wiring config to make my own?
