I'm on the road quite a bit and I listen to various books through the Audible app (bluetooth through iPhone X) as I drive. If I'm streaming a book from my iPhone (through the FR radio) at the same time as I'm using the Raptor's Navigation system, the navigation instructions do override the bluetooth (music, a book or whatever else I may be streaming) - as it should. However, the Audible narration continues as the navigation is speaking. So I'm having to constantly "rewind" the book narration so as not to miss parts of it. What I thought the A2DP was supposed to do is PAUSE the stream while the navigation instructions are coming through instead of allowing the bluetooth streaming to continue running in the background. Is that your understanding of how A2DP is supposed to work? Is there a setting on the Raptor menus somewhere that I can change? I couldn't find a setting on my iPhone to fix this either. This feature worked correctly on my old iPhone 8 and the Corvette that I used to have.
