as I suspected disconnecting the bluetooth obd2 connector did nothing to help me connect to the JB4 over bluetooth. it still can not detect it. I was able to set the map back to 0 turning off the JB4 using the steering wheel controls. I cleared the codes with Bimmerlink I will see if it comes back with the JB4 turned off. I did not find any loose connections on the JB4 so not sure why it stopped working
