I have this problem with my iphone SE and my Rav 4. With Bluetooth on, sometimes (not everytime) the radio stops playing and I have a message saying 'talking'. I've found two solutions, one is to turn bluetooth off on my phone, which isn't the best solution, two it would appear what is happening is that 'music' is connecting to the car radio, press play on the phone, then pause and we are back to normal, again this is not ideal.
I'm trying to find how to turn music off, which may solve the problem, anybody help on that one please?
Sometimes the problem occurs straight away when starting the car, a few seconds and I can do one of the two solutions, sometimes it's whilst driving so I have to find a safe place to stop to remedy.
By the way, I have updated to 10.1.1 using itunes, so have version 14B150. First few journeys I thought that had solved the problem, sadly not.
