I can only get navigation sounds on car speakers if I select MEDIA on car headset. (Vw discover navigation pro) so when i switch from media to say radio, I get no sound from either phone or car . I've tried different audio channels with no luck. If there was a "use phone speaker only " option I could just put up with that but without that the app is unusable.
Unless anyone knows how I can get app sounds on car while in radio mode ?
