How to install NTG4 DVD Map Update
I recently purchased a bootlegged copy of the 2016/2017 NTG4 DVD Map Update to load onto my 2009 C300 COMAND navigation system. I got 2 DVD discs but the person who sold me the software failed to include the installation instructions.
I thought it would be simple where you just insert the first and second map DVDs into the CD/DVD player and let them run by themselves but unfortunately it didn't do anything.
I looked on Youtube to see if there are any DIY videos and I wasn't able to find any. Do any of you guys have any information on how to install the updates?
Thanks!

Update: So the first disc was accepted by the COMAND system and it asked for the second disc to be inserted when disc one reached 96% (you were totally right). The problem I am now encountering is the COMAND system will not feed and accept disc two for some reason. The system will not allow me to select different menus and the disc feeder remains shut. Do I have to somehow forcibly remove the first disc or is there a trick to feed in the second disc?

just continue to try combinations of ejecting, go to different modes, with the selector, try selecting insert CD, continue to try every combination of the CD sub menu, the head unit eject button, and the CD load (when all the empty discs appear on the display).
I was really stuck on my friends 2009 GLK but it eventually allowed us to insert the 2nd disc. my GLK was more compliant but i had to get it to the menu where it shows the CDs on the screen first.

Are you in Australia? My disks are for North America (US and Canada).
If you need the disk, how do I send it to you?

hi there! in the off chance you see this, I’ve had an issue with my nav for a year. It’s been stuck on a rotating earth “awaiting navigation” for so long. It happened randomly one day during a back from local outing. Never any issues or anything. Dealer can’t seem to figure out why and keep saying a software update is needed but that I’m out of warranty? Anyway, I’m in Canada and have a 2017 c300 4matic sedan. If there’s any way you could send me the file as well, I’d be forever grateful.

Your Head Unit use "Software" not only for Map's.
Imagine that your unit it's just a little computer that has BIOS ( the bootloader SW) the OS and the programs.( also software ). One of the programs from third SW is the Navi.
Most likely both of us are off topic here, as your Head Unit could be NTG5, not NTG4.
So first you have to repair the unit - SW recovery or NAND memory replacement and after that you can read again my first reply as I was ready to offer a free Activation code for latest Map version available.

It either stays black or the screen has a rotating earth with activating nav going around. If I don’t exit the screen to media let’s say, the screen stays stuck on that nav screen until I turn the car off lock it and then after a few minutes, unlock and restart the car.

Again, I don’t know what a wireless MB update is is, let alone how to do it; I never knew updates were needed until this problem started and I researched what could be at issue, if it’s even a nav update. Total loss right now
