I'm currently using a 2004.2 Nav DVD in my '05 E320. Thanks to i12flytoday, I just updated my COMAND head unit software (version 46/06) so that I now have the option to display ETA at the bottom of the map.

I also tried to use a 2006.2 Nav DVD that I copied from a friend, but when I insert it into the Nav module I get a message that reads "No DVD. Please insert a Nav DVD".

I assume that I need to apply the Navigation Service Update as per DTB P-B-82.85/524a (AUG07). Can someone kindly tell me if applying this update will allow my Nav module to recognize the 2006.2 DVD?

To rule out the possibility that I am using an incompatible DVD or that my burning settings were bad, I made a duplicate copy of my 2004.2 DVD using the same disc type and burning procedure that I used for the 2006.2 DVD. My Nav module has no problem reading my copied 2004.2 DVD.

Any suggestions will be appreciated.

Sounds like a bad burn of the 2006.2 disc. I would try to burn it again from the original source and see what happens.

jkv11503

No dice. I burned it again but got the same message.

Does anyone know if the Navigation Service DVD mentioned in my first post will help me?

Benz-O-Rama

Yeah, if the burn wasn't bad then you most likely need to update your COMAND.

Thanks for the response, Benz. Did you mean to say that I need to update my Nav module that is in the trunk? Remember, I already updated my COMAND head unit using the software provided by i12flytoday. That (COMAND) update allows me to see the ETA at the bottom of the map; however, it does not let me use the 2006.2 DVD. I believe the COMAND update is seperate from the NAV module update.

JKV: what burning protocol did you use? I have never succeeded in getting a usable copy of a NAV DVD by using NERO. I think they make it difficult if not impossible deliberately. They certainly have a right to prevent unauthoirized copying, but all I want to do is have a back-up, which is usually permissible.

sgaar

It depends on what you are burning. If it just the ZIP with all the files it will never work. If you have an ISO that is created correctly it will work. Programs like DVD Decrypter will both create and burn an ISO perfectly. Don't bother with normal programs like Nero or similar.

starbrite

jkv, this may be obvious, but did you try the original disc in your car and did that work ?

Benz-O-Rama

I seem to remember people having problems skipping DVD release years. Meaning you couldn't go from 2004.X to 2006.X without going to 2005.X first.

With that said, I went from 2004 to a backup copy of 2006.1 with no problems. However, I updated my COMAND before going to a backup copy of 2006.2

Like Starbrite said, try the original 2006.2 disc and see if it works.

jkv11503

I used DVD Decrypter as was mentioned by sgaar. It let me read my 2004.2 DVD to an ISO file and then write (burn) it back to a new DVD.

jkv11503

Yeah, I wish I could. Unfortunately, I don't have access to the actual 2006.2 DVD as the files were provided to me online.

jkv11503

Are you saying that you have never applied a software update to the Navigation module that is in the trunk?

starbrite

There are no software updates to the module in the trunk. All software related Navi functions are in the Command module.

I have inserted (in the past) a new Nav disk into the unit in the trunk which caused a "Horizontal Status Guage" and the words "Installing Update" to immediately appear on my Comand Screen.

Of course, then my Comand became buggy in operation which required an update to the head unit software by the dealer to make everything work right again. That happend on my '04 E a couple of years after I got it. My guess is that there CAN be a nav update on certain Nav Map update disks.

Benz-O-Rama

Nope, never updated the module in the trunk. As Starbrite mentioned, that's not an upgradable component. However, every time I've put in a newer version map dvd, I've received the same message that Barry got. Which I believe updates the COMAND in some fashion.

Sounds like to me that you've got bad data that you're trying to burn. I'm guessing you FTP'd it down from a server somewhere and a few bits got lost.


How's your relationship with your dealer? Try asking them to "test" your Nav drive with a new disk to see if it will read it. That will tell if it's something with your COMAND/NAV or if it's your burn.

COMAND head unit service DVD special tool W211 589 14 22 00 – dealer net $12 allows ETA, etc.

“DVD not recognized” – Navigation module/processor service DVD special tool (as per P-B-82.85/524a) W211 589 15 22 00 – dealer net $12.

Eject existing navigation DVD, insert service DVD wait about 20 seconds the update process starts automatically and take about four minutes. Eject the service DVD, insert your latest navigation DVD you will notice the progress bars on the head unit this indicates the new navigation DVD is loading successfully. When completed turn ignition off and wait about three minutes to allow MOST and CAN to sleep. Turn ignition on, allow the navigation to warm start and acquire the satellites. Check navigation for correct operation by entering a destination.

Thanks, konigstiger. It helps to know that we are both on the same page. I was hoping to find someone who has experienced a problem similar to mine and was able to resolve it through the use of the DVD update mentioned above.

So, if I understand this correctly, even though the service DVD is inserted into the trunk mounted module, the COMAND module is what actually receives the update. Is that correct?

konigstiger

No, with W211 589 15 22 00 you will actually update the navigation processor in the trunk to recognize newer navigation DVDs. In effect as it pertains to your particular vehicle, you already updated the head unit software now you need to update the software to the navigation drive in the trunk to recognize your newer navigation DVD. Progress of the update will display in the head unit because the navigation drive is simply reading the service DVD.

I am not judging anyone here but it would appear someone has tried to obtain a copy of this DVD from the Internet and it hasn't worked? Could this 'pirate' copy have damaged this COMAND? Would buying a kosher copy actually resolve the issue?

I keep all my original DVD's in the house and have the copy in the car, this has never been a problem and I have never had difficulty using the copy.

Good luck getting this issue resolved

Excellent!! That is exactly what I suspected from the very beginning. I'll be paying a visit to my SA later this week to request the update to my Nav processor as per the DTB that was previously mentioned.

Thanks to everyone for the help.

jkv11503

No worries, John. It doesn't look like any damage was done to the COMAND based upon the fact that my 2004.2 DVD still works. It simply appears that my Nav module (processor) is not capable of recognizing the 2006.2 DVD, which is why Mercedes released a DTB to address this issue. Now, if only I could find a 'pirate' copy of that Navigation Service DVD...

Benz-O-Rama

Ahhhhhh,

I always thought the update was being done to the COMAND via the nav drive.

Thanks for clarifying.

starbrite

Yes, +1 , that's certainly news to me as well.

COMAND update (w211589142200) performed by inserting the service DVD into head unit single disc player.

Navigation module/processor update (w211589152200) performed by inserting service DVD into navigation drive in trunk.

I recently read that "the navigation processor software normally is on the Navigation disks itself and therefore updates when a new mapdisk is inserted - however there are also sometimes releases that are for the navigation processor and thus applied using the navigation processor's DVD drive." You can read the complete text here... http://www.mercupgrades.com/COMAND+A...faq-10.html#16

It's just a hunch but perhaps Navteq only includes the "processor update" portion with the initial release of each new mapdisk (i.e, update included on 2006.1 but not on 2006.2).

It doesn't really matter to me as long as I can get my Nav updated; however, I just thought that some of you might find this interesting.
