I presume you are talking about phone calls.

If so, try turning up the sync volume when your call is answered and whilst the person is actually speaking. The same applies to SatNav if you have that.
Also, ensure that you have done a sync master reset.

The radio and USB music works in a different way as far as volume is concerned.

Yes, I mean phone calls.
Voice navi works
But when making a call, the media option becomes dim and you cannot switch to Bluetooth. When you end the call, it returns to normal.

Restore the APIM from Jailbreak and reformat.

With Forscan, go to the “main module + hidden and engineering mode” configuration and look for the “TouchScreen” option. Select Sync 3 or “8-inch screen” there. This tells the BCM that your Sync 1 is now Sync 3. For other models, this usually has to be done through the ACM via AsBuilt, but for models like mine, the BCM controls this setting.

If you have not already you need to delete your old profile and start a new one.

What adapter are you using? If these is all the modules that you are seeing you have some serious problems. You should see at least 10-15 modules.

The settings you need to get to are:
Check your FCIM asbuilt for the following:
7A7-01-01 xxXX xxxx xxxx
If your OEM FCDIM asbuilt, it has ‘00’ entered there.
00=No Remote Display, APIM Not Present, ACCT Fixed, ATWU Not Supported, RAF Not Supported. PWMVBCBT VBC
Change the value to ‘60’ (or 20 if you get a not supported message)
60=Touchscreen Display, APIM Present, ACCT Fixed, ATWU Not Supported, RAF Not Supported. PWMVBCBT VBC

Also, look at the ACM, 727-01-01 Xxxx xxxx xxxx
If your OEM ACM asbuilt, it has ‘APIM Gen1’ entered there.
Change the value to ‘APIM Gen2’.
