I have a 2014 Subaru Outback & a Samsung Galaxy S6. I'm having the same problem with the Google Maps Voice not coming through the Bluetooth. If the Bluetooth is not working then the voice comes through the speakers just fine. Like the others posted, the voice would override whatever media or audio that was playing (incoming or outgoing phone calls, radio, iPod, Amazon Prime Music playing through my phone, etc...). I've followed the steps in the Google Maps settings ("play Voice during phone calls" and "play voice over Bluetooth" & volume on the loudest setting) and they match what has been posted in the great visual of the settings. I've even tried going through the Bluetooth Settings to click on/off the audio and media settings separately then both of them, every which way possible, and it still doesn't work. I went to Sprint and they said it was a Bluetooth issue and to un-pair it and re-pair it and that should fix the problem but it didn't. So frustrating and time consuming as it defeats the whole purpose of having the Bluetooth to voice turn-by-turn directions! Anyone have any other suggestions?Thanks so much!
