Got the new module installed last Wednesday. I personally refer to this is the mother board or CUP but regardless. Car is ok so far I think.
Two times now when talking on the phone the speakers stop broadcasting the conversation but the phone is still connected but I have to pick the phone up and talk without the feature of the bluetooth. Panel shows the phone is still connected to blue tooth but speakers don't broadcast sound.

 

My iphone Jag bluetooth connection work as they should. However, I did notice that when I first linked there were problems until I got the recognition sequence correct. Try deleting the current link between your phone and car. Then go back through the link process making sure the phone bluetooth is already in the discover mode before the car tries to discover it. Once I got that right phones are easily recognized , linked and function normally.
