Any ideas on how to have a Samsung Galaxy S3 play ALL audio through bluetooth to a car audio system? The BT pairing to my car audio system works very well for phone functions, but all other audio coming from the GS3 (TeleNav, music audio files, voice recording playback, etc.) goes out via the GS3's speaker or audio jack. I tried BTmono, and that kind of works for music audio files, but not at all for TeleNav audio or voice recording playback. Appreciate the thoughts.
