Any "hidden" features on the '04 symphony head unit?
Any features you can post would be greatly appreciated.
Actually, I've heard that the new head unit has a hidden mic to listen to outside noise and adjust volume to compensate. This is more advanced that previous systems that Audi has used which included a speed-related adjustment.
I wonder if there is a way to turn it on, as currently, it for SURE isn't working, as I am constantly adjusting the radio for volume compensation.
On my S4, i was able to turn up the speed-related volume sensitivity, and it was an amazingly useful feature. I just need to find a way to access these undocumented features on the TT now.
