iOS is primative compared with Android. There, you can manage phone and A2DP channels separately. But iOS lumps them together. Which means music starts playing every time I get in the car. My car (Scion) manages two channels separately. However, if I turn off the A2DP channel on car, it also disconnects phone channel. (Android worked great using only phone channel.)
I know there is a jailbreak way to fix this shortcoming of iOS, but is there a way in Spotify to control it alone? I go to the little blue button and switch it off car audio and on to phone, but it does not remember the setting and next time I get in car the same thing happens.
So I either have no bluetooth for phone, or I have music starting on its own which stinks.
