I use Spotify in my car with Waze, normally I connect my phone with Bluetooth to the car and listen to the music in my car stereo system. I would like to have the Spotify music transmittingin the car system and the Waze indications in the phone speaker, that way the indications would not stop my music. I activate this option in Waze (play sound to phone speaker) and this works, I get Spotify in Bluetooth speaker, and Waze in the phone! The problem is that when Waze is talking it mutes Spotify! Is there any thing I can do to keep the music running while Waze is talking the indications?
