May have been posted before but took me a while to find this out.
Out of the box Fiscon bluetooth unit does not have A2DP enabled so music can't be streamed to your stereo.
I thought it was a problem with my coding and went through set up many times with no luck but it is set up of the Fiscon unit.
Once installed and coded to your vehicle you wil have an option of "A2DP start" on the DIS from MFSW controls but it does not do anything.
With ignition on and phone connected dial *582#4001. This enables A2DP function.
Turn off ignition and wait 5 minutes then try to stream music.
