There are two separate Bluetooth protocols involved: one for phone calls, one for music/other generic audio. Maps and other apps only use BT music audio protocol which requires your radio to use the specific BT source, not the phone call protocol which auto switch to when ever there is a phone call but with much limited audio quality.This is a common issue. Same with me. It works when you use the Bluetooth source rather than leaving it on radio or other source. I just turn up phone volume
Google Maps or any other nav software never able to do that. I have a car that only support phone calls, not BT audio. In the old days, there are apps that allow you to route BT audio to BT phone protocols but those have long stopped working.Yeah, I have no problems with Audible books or any of my music apps. I thought I'd be able to hear directions through the radio speakers even while I had Sirius radio playing. you know - have it interrupt the music. If I have to keep the radio on Bluetooth to hear the directions...a lot of empty air.
Yep, that's what's required.If I have to keep the radio on Bluetooth to hear the directions...a lot of empty air.
