Upgraded to 3.4 from 3.0
Upgrade first appeared to be fine but wife took the car to work to have the sync basically crashed to black screen.
Power cycling brought it back to life.
It happened twice.
Did hard reset after upgrade as per guide so a bit concerned there’s something going on plus already getting the Mrs on my back as of course “I should never have touched it”
Any advice before she starts divorce proceedings…lol

I had this happen to me once but it was over a year ago back on a much older version of sync. I had to do a hard reboot as well with the buttons. Hasn’t happened to me since then. I’m not sure what causes it or of a potential fix.

Could try and run the interrogator log tool (under utilities in Syn3 Updater) to see how the APIM is set up.

I’ve seen this, but not often, right after an update including maps and Nav_voice. This might be due to the system still parsing the map and voice files for use on the system. It usually does not reappear after a hard reboot.
