Any chance you happen to know the latest code to get into the hidden menu on the EV6? Used to be 19190307, though it was changed in the 231215 infotainment firmware update.

I don't, sorry. I've held off on installing updates for exactly this reason. They seem to vary based on current year as well as firmware version - you might try rolling your system clock back to 2023 before trying again.

No worries! Thanks for the hint about the date -- I didn't know that was a function in the equation. Changing the date back to 2023 actually allowed the 19190301 code (had a typo in my original post) to work, though it seems they've removed the telematics switch unfortunately. Some day, I'll have to figure out how to disconnect the antenna.

That's disappointing - thanks for the info. I guess I'll continue to avoid infotainment updates. I can confirm that the telematics toggle is present (and functional) in the variant coding submenu on version 221025. I wonder what dealers are doing in Massachusetts now.

I think the antenna connectors are accessible if you remove the lower center console trim, then reach up behind the screen. But I haven't tried this, since the software toggle works for me.
