I did a SYNC update yesterday. Mine was still on whatever Lincoln was releasing on 7/12. Updated now to 3.8. It took just over 30 minutes to upload to the car with the poor car running the whole time, but the results are impressive.
The entire system seems to run quite a bit faster and vocal word recognition seems to be much, much improved. I had changed my wife's name to "The Woman" because the old system didn't recognize her fairly common name. So far it has been 100% since the update. I was even able to change my wife's name back in my phone. LOL
I seem to also now have some guidance from the system that I don't recall before. Upon saying the first command, the screen now shows suggestions for the next command. I don't recall that before.
First thing I did after pairing my phone again was to switch it back to advanced mode. I can't imagine living with those L...O...N...G drawn out voice prompts. I'm not patient enough for those.
