ios7 bluetooth issues with BMW

I updated to iOS 7 last week on my iPhone 5, in which I've only experienced problems when paired with my BMW. Detailed below:

1. While phone is in use (via Bluetooth), any occupant of my vehicle can clearly hear a persistent chirp coming from the speakers (over voice);
2. While streaming music, tracks are skipping as if a CD is attempting to continue playback after hitting a bump; and
3. Prior to upgrading from iOS 6, my music seamlessly picked up with the exact track (and location) where I previously left off

   I initially believed that code had been built-in for iTunes Radio to began by default until I realized that it was literally music from my library playing in a schuffled sequence...and I have created zero playlists within iTunes Radio for music to even stream.

I've done multiple hard resets of my phone; removed my phone from my car all together before pairing again; and updated to iOS 7.0.2, although nothing seems to correct this.

Has anyone experienced any of these issues, and if so, any success in resolving?
