So, you've confirmed that there are no updates. (my chat with Sync support today would only say no ETA on any updates)
I had the pairing issue a couple of times. The code would flash then say failed. I fixed this by pulling the fuse 29.
That fixed the pairing but as time went on, the BT Audio begins to fail and I still have to force the iPhone to re-connect to get it to notice the SYNC in audio mode
