Any way to reset the COMAND, specifically the Nav part of it? Since yesterday, I've been having a problem where the Nav is showing on the map that the car is about 50-200 feet off from where it really should be. It says that I have at least 6 sats, usually more, but it is just a little off. Last night it was much further off, where it was showing that I was on totally different streets.

Intgerested myself- today it located me in the middle of the Gulf of Mexico and refused to budge for 3 hr drive. Never could get a decent fix thus no way to set a route. Tried to stop and restart the car but that did nothing.

Is this a problem others are having or do I not understand something ?

Which navi-DVD do you have?

marksatex

Box says:
U0028-0070-309
North America DVD Pkg 2004-1
MBUSA part # B Q 646 0166

Any thoughts ?

MadManAboutTown

Geez, maybe it thinks you have one of those James Bond cars that can navigate across water

marksatex

That would explain why I could nevert get a tracking on it when it was shipped here last month.....

patrick

Are there any other numbers on the DVD itself, such as "2.0", "2.1" or "2.3"?

marksatex

says 2004.1 I notice it does not have some of the newer streets in my area. Will these be updated from time to time ?

I have had tons of problems with NAV, and in one of my early posts, mentioned how to reset the system. Here is what to do--by the way, you will be reseating some fuses, so don't blame me if this experiment either doesn't work for you or messes something up. It works for me (standard disclaimer):

In the trunk, remove the cover which lies over the POS that MB calls a spare tire. On the right side, you will see a foam cover for the battery. Remove it and you will see 3 fuses above the battery (a bit to the left). Use the pull-tool included with your kit (on the left next to the jack) to pull the three fuses (I don't remember exactly which one resets COMAND) and wait for ten seconds. Then re-seat the fuses. This will reset the entire COMAND system.

I am afraid this will only provide you folks with temporary reprieve. The issue seems to be with COMAND itself. It really has been incredibly troublesome for me, to the point that I wanted to shoot my car.

Hope this helps.

Make sure you have someone shoot a video, too so you can share your frustrations with your MBWorld pals

I am sure you guys know this, but if in case you don't, if you get larger wheel put on your car you MUST have the NAV reprogrammed by the dealer for obvious reasons.

These posts are all leading me to believe I should just go with an aftermarket NAV like the 2610.

bmms8

i didnt know this, what are the obvious reasons?

its connected by sat, so i dont understand how it would misplace you if you had larger wheels, can you explain it to me, thanks

monakh

I will do that Right after I shred the NAV DVD and listen with content to the grinding of the shredder as it tears apart the disc. OK, I am a sick man.

Well my service tech told me that the Nav does a combination of Sat and actual mileage traveled at the wheel to determine your location. Especially when you are out of a service area. So it gets really confused when the two don't jive.

Is this on the DVD itself?

US-DVD should be the same as those we use apart of having other streets on them. On every navi-DVD there is a software update package that should be the same for every Comand (211).

Overhere, those with the 2.3 software-update on it solve the navigation problems (showing wrong locations, shutting off, freezing,...).

(The TSB referring to this problems mentions also North American 211-Comands)

Oslo

W211 (and most other MB's navigation systems) are self-calibrating by continously comparing distances travelled with their map data, and correcting any differences. Some other manufacturers' systems can't do that nor use a manual tire calibration.

Dealer told me today that my version is the newest. The drop outs probably are atmospheric interferances and or interferances by proximity to cell towers, large power grids, hospitals. All seems logical on the surface guess I will be sure to keep a few maps in the trunk just in case. I notice that the number of satlites changes a lot so that must be very volitale. You watch in a few years we will have to pay an access charge to even use GPS.

Wish I could get in to the COMAND diagnostic mode to see what version I am at, but the Mute+1+3 combo does not work for me.

I think I'll give Mercedes a call and see what they say. Maybe I need the newest software update.

And, does anyone have the Star bulletin for the Nav update?

patrick

No.

If your dealer says "the newest", he means the latest HE can get.

Please read my postings about the 43/03-software.

Patrick: First of all, your comments are greatly appreciated.

Can you explain to us how a US dealer actually gets software updates? They way I understand my dealer's explanation, they must email the specific problem the car is encountering to "Germany", and await a response which is expected with one hour. Then a software fix may be attached which is specific for the car, and must be applied within a limited time. The specific issue dealt with engine management, and they said the factory concern with applying fixes was modification of US emission controls via software. Am I understanding this accurately, and does it apply to accessory electronics as well? Is it the same in Europe? Thanks in advance.

marksatex

I probably need to ask Service as my experiance with the sales guys is that they say anything to make all seem ok.
