Upgraded to 2023.27.6 last night, now navigation audio is unintelligible. Radio still works fine, but navigation instructions only come out of the subwoofer. Tried rebooting twice with no effect.
I turned off audio directions almost immediately after getting the car so probably would never have noticed!
Update: My car was serviced last night (2023-10-31) to fix this. It has been fixed for $190, but all they said about what was fixed was the following: Correction: X057 Connector Soft Set - Inspection I asked through the app what was found and how it was fixed, but got no response. X057 appears to be an identifier for a connector, but I can’t figure out from the wiring diagrams I have for the car where that connector would be. It appears the audio signals go through that connector, but that does not explain why the radio sounded fine, and only the navigation audio was unintelligible.
