Software updates

Is there a way to get command unit software updates anywhere? Dealer charging outrageous fees.

Are your trying to update the firmware of the Comand unit to fix a problem or enable a feature?

Or are you trying to update the navigation database? If it's the database, there are multiple options for DIY database updates. (example)

That said, the GL X166 is perhaps the easiest of all MB vehicles to add an aftermarket box to enable Apple CarPlay or Android Auto with the OEM screen. There's literally only 2 screws involved. Alternatively, it's also possible to replace/upgrade the NAV screen with a larger unit that also enables CarPlay and Android Auto. There's multiple threads for both aftermarket options.

I had the dealer run diagnosis when the car was in a shop earlier this month and one of the error codes state that theres a comm error.I am trying to update the firmware because there is a communication problem between 360 camera and the command unit. It's rear cam is completely black. I got it to work couple of times after disconnecting and reconnecting battery. I also removed the liftgate trim and tried troubleshooting connections there but no luck. I researched the issue quite a bit and it seems like may be resolved by software updates.

I'll eventually that the joyeauto interface box. Not sure if that would help get the rear cam feed back into the screen?

FWIW, all these aftermarket boxes work by inserting themselves in the video path between the Comand unit and the screen, so as a result you should not expect them to fix the problem with your cameras. The OEM cameras communicate directly with the Comand unit.

Once you have the cameras working and want to get install an aftermarket box, consider a newer generation unit (like RoadTop) rather than the earlier Joyeauto unit. (I have both). That, or go all in and get one of the units with a larger screen.

Is this the option that you would recommend for a 2013 GL450 (X166)?

Yes

Note that there are multiple channels that sell outwardly similar "RoadTop" units and I don't know if they are related. FWIW, these units are also available via Aliexpress and Amazon depending on your location.
