OK, so I've noticed since I bought my phone that while I'm driving to work, with the bluetooth on on my headset, and when I plug in the Aux 3.5mm cable into the phone, the music transfers to the Car Audio system like it's supposed to. Keep in mind I just bought my Nexus 5 last week. While into my drive (10 to 15 minutes), all of a sudden the music stops playing in the car and switches automatically back to the headset. What's causing this? Anyone experience the same issue? I know I can turn off my bluetooth headset, but if I get a call, I want to able to answer it quickly. I'm currently using the A2DP Plantronics M50.
Another issue not in the subject because I was cut off from the character limit:
How come when I have bluetooth turned on and answer the phone physically on the phone by swiping the call answer icon to the right, the audio automatically defaults to the bluetooth headset. Why? It should route the audio to the phones earpiece, not the bluetooth. If I wanted to answer with bluetooth, I would press the bluetooth answer button. This happened on my Nexus 4 as well.
Anyone with info please?
