I just started a 4000 miles road trip and my drive assist won't engage. I noticed also that the car isn't reading speed limit signs (related I think). Anyone else encounter this on 2.8.0? Advice to fix? Thanks!
 
Have you tried rebooting the vehicle yet? Also, are you seeing any yellow triangle warnings on the lower edge of the driver's screen? Any warnings can also prevent DA from working.
 
Are you saying it is reading speed limit signs incorrectly, or not seeing them at all? FWIW, my Air is always giving incorrect speed limits

It's not reading the signs at all, the display is just showing a blank white circle with a red border around it and two underscores within.

No warnings, and I've done both a soft and a hard reset.

No warnings, and I've done both a soft and a hard reset. My native navigation isn't working either (shows me still at home). Any ideas what this could be and how I can fix this would be greatly appreciated!

Try to go offline in maps and disable it again. This may fix the location issue.
 
Sounds like a TCU/connectivity issue. That circle speed limit is the EU version, which normally only appears briefly during boot before the car realizes it hasn't jumped an ocean. You may need service to reset that if leaving the car alone overnight doesn't fix it. Do the built-in media apps work?
 
Thanks for everyone's help. I woke up for day 2 on the road and everything worked again!
It must have been the car's prolonged sleep that reset everything.
