I have an iPhone 7 with iOS11.4 and an avic8000 with firmware 1.15
i havent updated since 1.04 and before updating recently I was on a Bluetooth call where the call audio broke up and started to sound “digital” or robotic.
Ended call and wasn’t able to get normal BT volume so I upgraded to firmware 1.15 and updated my phone software and still same issue
music, maps, email alerts - any type of Bluetooth transmission EXCEPT a phone call is working st correct volume.
Phone volue is definitely up.
I’ve noticed a few threads with this iss
