I just got a new 2014 Chevy Sonic and I have paired my Huawei H881C to the car stereo. Once for "Phone" and once for "Music". Right now I can play the car radio music OR press a button on the car stereo that says "Media" and select "Bluetooth" which turns the car radio music off and lets the GPS voice directions come through the car stereo speakers but no music. I can't have both, the car radio music and GPS voice directions at the same time. Seems like the music volume should mute while the GPS directions are given then return to the previous volume and continue playing the music I had going. Instead it's "either or". Is there a setting I'm missing somewhere?
