Default Bluetooth Telephone Issue

Sorry to make a new thread, but I successfully got my bluetooth module working. However there are a few unique issues. The first thing I noticed was that, when receiving a call there is not audible ringing, letting you know someone is calling, and once you answer the call I could not hear them but they could hear me. The second issue is once a call, that was placed or received is over the music from radio/ami/cd will not resume and the AMI displays, which can not be unpaused:


The only way to get the audio to resume is to reset the MMI. I am currently updated to 46.1.0 on the MMI, however my bluetooth module is currently:

which ever helps best identify the SW level. Now that I think of it. Whenever I updated my MMI system I didn't have the bluetooth telephone installed. Are the issues described above why there is a special bluetooth disc included with the 46.1.0 update? Do I need to rerun the 46.1.0 update now that I have the BT telephone installed or just run the bluetooth disc? Any opinions will be helpful, I am quite honestly surprised that I got the BT to work this much so far.

The sequence of MMI 4610 followed by BT install could be your problem. No telling what software versions are loaded onto the BT module and if they are pre-4610, that could explain your issues. I would try running the Bluetooth disc first - if it will load by itself - otherwise I would rerun the 4610 update.

Turns out that the coding in the control head was incorrect, for the mute "feature". I had Mute-Wire active in my coding for the control head. When, it should have been Soft-Mute and Line-In active (for Telephone Retrofitting). Thankfully all is working well.
