Hello, I just picked up my new lumia 520 and noticed that while in the car it will randomly pause mp3 music for 2-3 seconds. Its not every song, but its extremely frequent. It does not appear to do this while listening with headphones. I am connected to my car via bluetooth and using Here drive for GPS. Here Drive is in offline mode, and the phone is being used for wifi only, no phone plan. It has an AT&T sim in it purely for the clock to function. I do have the black update, but it did this problem with the amber update as well. I have disabled all backround processes I could.
