Bluetooth issue with streaming

[mweathers]

I have the Optimus V, SW version VM670ZV4. I've been streaming Pandora and other music to my 2012 Elantra with no issues....until yesterday. Now nothing will stream! It plays on the phone, but I get a message that Phone music is unable to play on my car system. If I hit pause, the music stops on the phone. So I know a signal is getting to the car. I've reset the car system, and also repaired the phone to it....with no success. What made this happen, and how can I fix it? If you need more info, let me know. And thanks!
