I recently got an 06 caravan sxt. It has the oem u connect with the u connect buttons on the rear view mirror. I also have an rca inout interface adapter to be able to put rca inputs into the radio. The u connect has to be unplugged from the radio to plug inthe interface adapter. I need a harness adpter to plug in both or some way for both to work. I dontreally want to unplug the u-connect feature. HELP ???
