I think it would be a wiser idea to use a high power FM transmitter rather than bluetooth as bluetooth has a delay which is different every time you connect to it... you can't predict the delay... also you lose the ability to connect your phone

A high power FM transmitter would eliminate the lag as well as the issue not being able to connect your phone

and I mean high power because cheap ebay FM transmitters do not output enough power thus the low quality and static

Yes, this would be cool. I hate to switch between bluetooth devices while using both iPad and iPhone in the car...

The Model S’s FM also has a lag. My Christmas lights that I put up has an FM channel to tune to, and I always notice it looks out of sync on the Model S.

did another field test today. Played YouTube song with the audio sync-ed with Bluetooth, found delay in aux transmission ~100ms.

The MHL is not function, might be the hardware issue, need to figure out
