Hi, a couple of weeks ago (early May 2024) my wife told me her 2022 GLS 450 prompted her to okay a software update. She followed the prompts and everything seems to have updated properly. Does anyone know what was updated? Sounded cool and wish I was there to see it!

Likely the map update for your home area. The map on my 2020 was updated over the air on 5/15.
You can check on the Mercedes me connect app.

I received this update last Friday.

I had 2 separate updates within the same week, one for the map and one for MBUX improvement per jtjbt20x's post.

Hi, yes, looks like one is for the maps and the other MBUX. I hope the update doesn’t wipe out the ILS programming RJA did for me!

I had the light coding done a few years ago. Had a bunch of updates since and none has wiped out the the functionality, but somewhere along the line I did lose the menu item to turn them on or off. They will recode for you if you want, but I'll probably only do so when I go to sell or something....

FWIW, I did lose the light coding done by RJ. Now, I need to figure out how to get it back.

I believe they will recode for free, so that's the option to get it back.

Now will have to check to see if I've lost mine. Haven't driven at night since the update last week...

Just as an aside, I'm in Tennessee, so the over the air update is only for Tennessee, Kentucky, and Ohio. This does not help me as I rarely travel north. In December 2022 after purchasing the vehicle I downloaded other maps to a thumb drive and installed them in the vehicle, in a very easy process. The past few days I have been trying to do that again, but get the message on the website that "The service is unavailable for technical reasons." I called Mercedes me connect yesterday, and the issue was upgraded to another team for resolution.

The map updates (which is different than this OTA system update) that are done automatically over the air are for one region only, and unfortunately the regions don't always make sense (but you can change the single region -- although changing it to one without your home state probably isn't bet either). The on-line download service update of the entire country seems to go down for a few days at a time pretty regularly, I just keep trying and eventually it works. I did this most recent update 2 weeks ago, so give it a check once a day or so and it will come back at some point for you to do the download.
