        With iOS 10.3 a bluetooth issue is present (again) where the audio of phone calls is not routed to the bluetooth device. When setting up a call from the bluetooth device iPhone shows that audio is routed to the iPhone itself in stead of bluetooth device. Microphone and speaker of iPhone are used. Audio of phone calls is routed to bluetooth device only if manually switched from iPhone to bluetooth device

         

        Issue: Music audio is routed correctly but audio of phone calls has to be switched always manually to the bluetooth device in a BMW with infotainment version MN/TN 003.013.001

         

        Tried but doesn't fix:

        • Change setting "Call Audio Routing" from automatically to Bluetooth
        • Restart the iPhone
        • Forget and repair the devices .
        • Reset Network Settings

         

        • Problem was not present with IOS 10.2 and 10.2.1

        All 10.3 betas

        • problem was introduced with IOS 10.3 beta 1
        • Update: problem still exists with IOS 10.3 beta 2
        • Update: problem still exists with IOS 10.3 beta 3
        • Update: problem still exists with IOS 10.3 beta 4
        • Update: problem still exists with IOS 10.3 beta 5
        • Update: problem still exists with IOS 10.3 beta 6

        • Update: problem still exists with IOS 10.3.1
        • Update: problem still exists with IOS 10.3.2

         

        Beta 10.3.3

        Update: problem is solved with IOS 10.3.3 beta 1

         

        With every new release of IOS bluetooth issues are a recurring issue. It seems there is a major issue with the bluetooth libraries Apple is using during development.

         

        A special note to the Apple Bluetooth team:

        I don't know what the Apple Bluetooth team has fixed regarding Bluetooth with IOS 10.3.3 beta 1 but please keep your utmost focus on future IOS releases since handsfree calling is a safety feature and should never be compromised.
