Well, looks like my sync upgraded (2017 502A). I can only tell because the font is slightly different....

However, now:

1) I get a message everytime I start that says "you can upgrade software by finding a network"
2) My Android auto no longer auto starts when I plug into the USB (in front)

Any other Android Auto users out there have a similar experience - found anything helpful?

 

I'm in an 18 502a and have seen 2 intermittently over the past week....nothing I can do makes AA start....and then all of a sudden it works again. I don't know if it has updated recently but I do have it on auto update and wifi is in reach of my driveway

 

1) Turn off auto update.
2) I had to uninstall AA and reinstall running setup again. If that fails then a master reset on your Sync3 should work.
