Help Samsung S3 Bluetooth issues



Ever since I upgraded my Galaxy S3 to 4.1.1 (baseband I747MVLLH1) I have all kinds of issues playing music through my car's Bluetooth. I just did factory reset and tried, and still no go. The phone connects and I can see the song info on the car's radio. I can even pause and resume it through the radio but the sound is coming from the phone's speaker and not the car's. Is anyone familiar with the issue? Also the Media player sometimes will crash when attempting to play music through Bluetooth, but it will work when playing through headphones.
