Bluetooth problems: 09-x5, 30i Xdrive
 

So I am having this problem with my BT as well. Not working now. It started out that my nav system would freeze up. I kinda traced the problem to the BT module so I disconnected it. Now eveything else is working except for BT and the USB in my console.

My question is...if I buy a so called good used one on say ebay. I found one that is the exact unit number for number but I am afraid to buy it. Because I need to know if these modules are plug & play. Does anyone know? Any thoughts on this? Thanks!
