Navigation no longer working
"The system software has been updated. The map software must be updated now. Please insert the DVD with the map software now."
I can't find any disk form my user manual and I took the car to the dealer. They told me that they can't read the processor and diagnosed it as "internal failure of navigation processor" and will need an arm and leg to fix it. I'm puzzled since the message implied that it's looking for an updated map software. Is this related to updated maps with "bird's eye view" etc.
Has anyone experienced a similar issue? Thanks.

Did you try to insert a maps update DVD?
If this happened unexpectedly on its own, then sounds like the HDD has failed and got corrupt data. This would explain why the dealer was not able to reach the unit with diagnosis tools.
The only dealer solution may be a new head unit (swap part could be reasonable).

This happened unexpectedly, went to start the car as usual, hit the Nav button and got this message. Where do you get the maps DVD? Our car didn't come with any DVDs. he dealer said DVDs came with older cars.
Dealer said they need to replace the hard drive. Radio, phone and everything else still works, just navigation is kaput.

You might ask dealers in your are if they do this type of work or can send your Comand unit to a repair shop. I don't know if your vehicle can be driven with the unit removed.
Another problem may be the availability of a replacement HDD. Most, if not all, disk drives manufactured in the last couple of years use the serial ATA interface. It is likely that our vehicles use the older interface.
You might want to investigate the availability of a unit from a junked vehicle. There are several companies that you can locate via Google.
Your dealer should be able to tell you the range of vehicle model years that are compatible with your vehicle.

I hate to say you may want to wait to do anything. I started to receive exactly the same message on my 08 S550 and no nav. I really never use the navigation and just left it alone since everything else worked fine (I did purchase a new DVD update disk that I could never get to work). After about 5 or 6 months lo and behold it started working. I slipped in the update disk and everything updated (took 1/2 an hour) and the navi is just fine. ??? maybe the system did not like the winters here in Arizona and likes the heat.

I thought about purchasing an updated maps DVD to see if it works but guess you tried it and it seemed like your NAV fixed itself. I'm in the same boat, i.e., don't use the nav except wife does and would like to get it working again for her.
I'll try another dealer next week to get a 2nd opinion since we'll be on the road this week, without NAV, lol.
I ignored replacing the HDD as suggested by my dealer and MBUSA since I felt the price was high. Today, for some unknown reasons, the NAV came back from the dead after 2 months!
Restart the engine and it works fine. This started about a month ago.
yes, it is strange that several of us having this same problem all almost-at-the-same time.
or we need dealer to replace the whole command unit?
thanks

I have not seen anyone attempting a full copy, would indeed be useful to know if a full backup/restore to a new HDD would work without any issues with theft protection. If the present HDD is misbehaving, it would be time to take a backup, and it might still not be too late.
Hopefully someone shares his/her experience/knowledge on the topic.

displayed,
is it just the Navigation or the WHOLE command that does not work?
Sometimes when this is done the car getting a different HU may have to be reflashed at the dealer. I've only had this happen once since 2006.

I was at Mercedes workshop in Berlin (Klaus Bechmann) and they could fix it for €4000 (!!). They would then swap the whole unit.
The unit cost was about €3000, so they recommended me to get a TomTom instead.
Thanks!
