MERCEDES Comand APS NTG1 - HELP

Hi,
I have a Comand APS NTG1 on my European 2003 W211 E-Class with maps v19.

Past week I updated the Firmware of the Head Unit to version 30/06 (v21)
EU E,CLS HeadUnit W211 589 13 22 00 SW-REL 21.090 30/06 - According to Mercupgrades -> [Please Register or Login to download file]

RESULT:
- Procedure for accesing Engineering Menu changed to -> MUTE + Left-down arrow + Left-upper arrow + AUDIO
- 2nd hidden menu LOST - No option to unlock DVD while driving
- NAV system lost with a permanent blue screen - but the name of the roads are right displayed in dashboar so, DVD is right and CAN is working.

Possible fix with:
- A previous firmware version:
-- EU E,CLS HeadUnit W211 589 10 22 00 SW-Rel 15.130 Build 51/05
-- EU E,CLS HeadUnit W211 589 06 22 00 SW-Rel 9.390 Build 17/04
-- EU E,CLS HeadUnit W211 589 00 22 00 SW-Rel 7.130 11-06-2003

I've searched for any topic with "NTG1" word but, all of them are outdated and links not working.

I've asked to my Mercedes local dealer and this software is not available even for them.

I'm searching and asking for help at any forum I know I can ask but, at this moment, nothing.

I'd be very grateful if someone could help me in this issue.

Thanks in advance.

I have W211 15/04 (9.390) firmware and some of the old map dvd's

Once ripped the CD I've tried to update the firmware but no success.

I suppose my only chance is to try the update from a valid DVD with version v10-v15.
In your post you say you have some old map DVD's.

I don't suppose you could post a link to one of them?

I'd be very greateful to you.

I have V8-12-13, which one do you prefer ?

I've read the v12 is the best for recovering.

Let's try it

And thanks again for your help.

Here you have V12 (3 parts)

Your maps worked, but blue screen hasn't been fixed.

I know your map's DVD is working because I can read the road's name in the dashboard but main problem remains.

Thank you very much for your contribution

Just you let you know that today my Navigation module is fixed (at this moment)

During past two days I've been doing a mix of all the actions I read.

I post it here to make them known:
- Let die all the systems. Disconnecting the battery for more than a hour.
- Reinstall Firmware 30/06 in headunit
- Switch off everything during more than a hour.
- At this point, I recovered the Engineering Menu.
- Instroducing DVD with v12 maps in the navigation module in the trunk.
- When DVD stopped, switching off the car for more than a hour.
- Install DVD with v19 maps in the navigation module in the trunk
- When DVD stopped, switching off the car for more than a hour.
- Install DVD with v19 maps in the headunit.
- When DVD stopped, switching off the car for more than a hour.
- After this time, switched on everything, and before swithing off, retiring fuse 3 in the trunk.
- Switching off the car for more than a hour.
- When back, I switched everything without fuse. At this point, I must tell a note. Tyre pressure indication started to work in the dashboard. I'd never seen it to work in my car.
- Switching off the car for more than a hour.
- DVD with v19 maps in the trunk and...working. But Tyre pressure was mising again.

As I told you in any post you contributed, thank you so much for your contribution. ¡¡

Great you got it fixed

According to the guy from mbclub, Mercedes don't even know how to solve it
