COMAND UNIT FAILED
How common is it for these to blow.
List Prices: Comand NZ$ 10200
Ignition NZ$ 700
New ML 350 CDI NZD 125000 +
Some of the 2009 ML EIS did not work with the PIN code system, and it looks like yours was one of those and thus needed a new EIS ..
What was broken about your NTG2.5? What most dealers don't know is that it is often the hard disk and Mercedes sell replacements for NTG2.5 ..

The visit to the Auto Sound shop was just to borrow the old unit.
They had not replaced any of the ones that read the PIN from the EIS in a ML. So they claimed they had to get the EIS first, I think coded for the vehicle, then get the green key coded for the EIS.
Ours was sold new March 09. To program the second key only took a few minutes.

When the unit started failing my wife said the screen had a message something about updating and a progress bar started showing across the bottom of the screen and then dissappeared. The screen then showed the Mercedes symbol and the radio would play for a few seconds then it would make a popping noise and radio would stop. Then the screen would start up again with the Mercedes symbol and this process would repeat again (minus the updating and progress bar).
Interesting about the hard drive.
I would have to ask them what happened to it but I doubt whether they could answer! I would certainly be looking into this if we were paying!
