Do the map updates require a firmware update?
I have experience the same situation. And i must warn you that if you update till V11 there should be no problem.
If you update to V12, you are in a serious situation that your unit will enter in a loop mode. I updated my unit from V11 to V12 without updating firmware and go my unit to loop. And there was nothing that i could do then. My solution was to get my car to a Mercedes dealer and tell them to update the firmware. They thought that i wanted the maps but i insisted that i wanted the firmware only! That cost me 40 € in Portugal.
So my advice to you is, update the firmware in the dealer (it can only be updated there) and then in your home update the maps.
If you require firmware versions to compare, just ask for and i will tell you firmware version before and after.

My NTG4 unit version before firmware update was:
FL Ver.: BLD-NR-204 1.43
Navi Ver.: 01.15.08_ECE
CPU Ver.: 10200:00
SWDL Ver.: 91.15.01
Maps version: V11
So now my NTG4 Command unit version is:
FL Ver.: BLD-NR-204 1.45
Navi Ver.: 02.15.01_ECE
CPU Ver.: 10200:00
SWDL Ver.: 11.15.00
Maps version: V12 (2014 / 2015)
Map navteq ES1800-00 13Q2
But i must say that some w204 2008 - 2011 with NTG4 have newer firmware as this:
BLD-NR-204 2.02
04.02.10_ECE
Maybe those newer units with different hardware.
In my case, the dealer told me that they connected the car to the STAR diagnosis and they updated with the firmware that was available to my VIN.
Hope it helps you...

Well, i just know that in european cars that can happen. Because the information i got, is from a european ntg4 group. Dont know if that applies to American versions.
That bit of information to put the 2nd disk in slot 2 is incorrect, because when disk 1 is finish, the NTG4 unit will eject disk1 and ask for disk2! But is just a matter of procede with the installation and will see what happens.
To your last question, dont know for sure. With mine, dealer got it to work. But i have heard others that they needed to buy the HDD with newer firmware and then update the firmware.
My advice: get the firmware update! And get first a quote for that, the firmware and not the maps! Just the firmware.

Is there a way to bring the original unit back to life?
Maybe you got a bad copy? Do you still have the disks?
I still have no idea why this happens to some and not others. Have you been updating regularly?So before this version you had the version right before it?
