22 GLS 450 19 CLS 450
New user, lots of questions, kinda lazy, please be nice.
Long time lurker, first time poster. I just a 22 GLS 450 today and I have some questions about features I'm familiar with from my previous MB experiences. And I know probably all of these have been asked and answered but since there were so many I figured it would be easier to just post them instead of trying to chip away one by one. Any help would be appreciated and if you don't want to help and call me a lazy clown that's fine too because that's logic that's tough to argue with if you ask anyone who knows me. Here goes...
1) Is it possible to make the HUD smaller on this car? I'm coming from a CLS 450 with a nice, proportionate HUD and this one is enormous and more distracting than helpful if I can't make it smaller. I got it up and down. I got it brighter but I can't see anything that will make it smaller
2) Is there any way anyone knows of to manually lower or raise the third row seat? The motor on mine is burned out and it keeps triggering an error. I'd like to force it all one way or the other until I can get it in.
3) Does anyone know what controls the heated arm rests? Are they tied to the heated seats of the climate system or just totally on their own circuit. Damn near burnt my arm off earlier. Nice feature though
4) Does anyone know what "automatic lock" does in the settings? Not acoustic lock, automatic lock.
5) I watched a video on how to add a second car to the ME app but I think it was outdated and trying to repeat the same steps did not work. Any advice on how to get this new car in here without deleting my CLS?
6) I saved the dumbest for last. What are the buttons in the cup holder for? I didn't get the h/c ones just the stock one

Sounds like you've already found the only two adjustments I'm aware of: Brightness and Vertical Height Adjustment. I do not believe there is a way to "make it smaller."
2) Is there any way anyone knows of to manually lower or raise the third row seat? The motor on mine is burned out and it keeps triggering an error. I'd like to force it all one way or the other until I can get it in.
There may be something a service tech can do manually, but I don't believe there's any manual adjustment of the 3rd row for us "end users." Only the buttons to power fully up or fully down.
3) Does anyone know what controls the heated arm rests? Are they tied to the heated seats of the climate system or just totally on their own circuit. Damn near burnt my arm off earlier. Nice feature though
The heated armrests are linked to the front heated seats. The center heated armrest will come on if either front seat heater is activated. The front door armrests are linked to individual front seat heaters.
4) Does anyone know what "automatic lock" does in the settings? Not acoustic lock, automatic lock.
If you engage "Automatic Lock," then the vehicle will lock once you hit a certain vehicle speed (I think it's approx 8mph).
5) I watched a video on how to add a second car to the ME app but I think it was outdated and trying to repeat the same steps did not work. Any advice on how to get this new car in here without deleting my CLS?
Yes, it's definitely possible to have two Mercedes in the ME app. When I did it, I scanned a QR code somewhere in MBUX, in order for the app to accept it.
6) I saved the dumbest for last. What are the buttons in the cup holder for? I didn't get the h/c ones just the stock one.
The manual only references the heated/cooled function. If you don't have that function, then someone else will have to chime in. My guess, from previous Mercedes models, is that the button may release a part of the cup holder, in order for you to remove it for easy cleaning. Or, the button may allow you to alter the size of the cup holder, to accommodate different sized drinks.

This was actually super helpful, all around thank you very much. I'm a little disappointed that I can't shrink the HUD though. I can't for the life of my understand why they made this display so freaking big. It's more of a distraction than an aid with it being so huge like this.

You are correct, it is a projector. The throw distance would only come into play though if I wanted to make it bigger. Then I would have to move it farther away from the glass assuming that the projector is at it's max display. Making it slammer could be accomplished by tuning just like you would with a home theater projector. Without seeing it, it's hard to describe but to compare, the display on my CLS takes up about as much real estate as a stick of gum that floats just off the hood and onto the roadway and the HUD on the GLS is about the side of a loaf of bread that projects over the entire width of a two lane roadway and based on my seating position trying to lower it to be less invasive starts cutting off the information.

I believe this is my 3rd or 4th car with some type of HUD and without a doubt this is the most dangerous one. I'd rather not know how fast I was going than slam into the rear of a semi I couldn't see because there was a giant 65 MPH display obscuring it.
Maybe one of these little system hacker guys will eventually find a way to sell a mod to make it smaller.

I was somewhat disappointed that our new to us GLS 580 doesn't have the HUD but maybe that's a good thing based on the thread.

I have about 130 pairs of my sons broken eye glasses here so maybe I will try to fashion a reverse telescope 
. I don't think you are missing much, I'm a little disappointed to be honest and probably will end up disabling it unless I can figure out a solution. It's literally bigger than the display on the dashboard, it's ridiculously too large.

The button on the cup holders pushed out an extra piece that makes the cup holder go around further and become a little smaller.

I adjusted it vertically to move it out of the way a bit more than factory setting, but to suggest that it obscures the field of vision sounds a bit extreme. There are times when I catch myself looking at the physical cluster because I forget the HUD is there. There are different settings, including a minimalist one that only shows the speed and not much else. I, for one, like having the map there, too.

I mean if I had to pick one, I'd pick the upgraded speaker package all day. So I'm with you on that.

If that is really the case then I have to be missing something. I will take a picture later when I head up but last night when I was driving I centered myself and the far right edge was across the white line and the far left edge was about halfway into the oncoming lane. If there is a minimalist setting I haven't' been able to find it yet.

Not knowing what the resolution of the HUD is it may not be possible to make it smaller in code. A physical mod like a lens over the HUD projector might do the job though, think the opposite of a magnifying glass. Much easier said than done I'm sure.

I watched a video similar to this to access mine. I think that if you have the time and the patience to spend with it that it's quite a worthwhile option. Since I was able to get in there and mess with mine it's a 180 degree improvement over how it was when the car was delivered to me.
The interface leaves a lot to be desired though and the fact you only have the stupid little thumb trackpad to make these adjustments just compounds the frustration of having to do all this yourself.
I do also recommend a full reset and starting over if things get out of wack. Since there are no values on most of the choices all you have is the clicking and your memory to know where you are from start.
If you spend the time with it though you should get favorable results like I did.
