Re how to fix -- nav database updates that "don't work" unexpectedly (that is, not due to known update errors) are rare here -- so, this is outside our experience.

My personal experience (on a NAR NH+ system) has been that all nav database updates after the initial update from production needed to be done as User-defined selections -- in this case, "updating" to an earlier version must be done as a full User-defined update (that is, all sub components of the release must be selected manually).

how do I initialise the user defined thing as I checked the box in the Swdl section of the greenmenu but when Ithen did a reboot and started 32.1 it wouldn’t let me do user defined? Have I got to save that change somehow rather than reboot out of the green menu?

Exit the GEM simply pressing another center console key; this GEM setting is not persistent, and is reset when the MMI system starts. Or, see my remarks in post #333, above. --g

ok so I reloaded 32.1 and all is well again so I think ill just leave it there and not worry about 35.1, not worth the hassle and fear of bricking anything

thanks for all advice peeps

@patroclox : You need to enable User-defined software update in the Green Engineering Menu, since K0257_6_D1 is the latest for EU MMI 3G High (HNav) systems. You might also look at editing the metainfo2.txt file to enable User-defined installation (this from the 3G+ thread):

Q. Is there a way to use used defined mode w/o "Green Menu"?​

A. Yes. In file metainfo2.txt in the root folder if you remove the line "MetafileChecksum=XXXXXX" and add​

EnableUserDefinedSWDLMode = "true"​

skipMetaCRC = "true"​

then you will be able to use the user mode w/o the green menu.​

Hello, I have accessed the installation with "user defined", but I have no option to reinstall or update, it appears in gray, and in principle I cannot mark anything to cause the update.
you can help?

@patroclox : Select all of the "Application" choices -- do not select any "Bootloader" choices ever ! Ideally, you should only need to re-install the software components for your Main Unit (MU9xxx), as none of the other MMI devices (like the radio tuner you show, above) affect how Navigation works (except, maybe the GPS). --g

I have Software version - HNav_EU_K0206_3_D1 and nav database version 8R0060884N ECE 5.12.5 on an audi a6 S-Line. Is there a particular file i need or can i go strait to the latest?

Sorry again, either I'm very clumsy or this system is very complicated.
I have entered the categories MU9308 and MuIOC --> Main, but I cannot select anything from the application or anything.
In MuIOC I get this message that can be helpful "Update Bootloader only with application", but I can't select or activate anything there either.
Thanks.

 

[DrGER]

@patroclox : I would expect that "updating" only device MU9308 is needed here, and that the "Aplicacion" items are all selectable (that is, by pressing the SELECT button when the item is highlighted in white). If the "Aplicacion" items are not selectable for you, someone else here will need to offer a suggestion on how to make them selectable for you. --g

Can someone send me the previous version? maybe i can try a downgrade

HNav_EU_K0257_5_D1

 

[DrGER]

@patroclox : For EU HNav firmware, look here: MMI 3G navigation 6.24.2 Europe and firmware updates -... and here: 33.55 GB folder on MEGA --g

All MMI updates are complete (that is, they are not incremental). You can always install the latest version directly. --g

Created an account on mega and started to download 8R0051884KB_6.35.1 etc.

Halted at 5gb, Is there a alternative link to download or am I doing something wrong?

Thanks

 

[JohnS4]

You hit your free account limit on mega. Pay £5 for a months access and download it all in one go.

Hello !

Actual firmware is hnav k0206
Maps are 5.12.5
Do i need to update firmware too or just maps and activator ?
Thanks

 

[JulianHicks]

@kmaci27, I don't think you need to update the MMI from 0206 to 0257 but as it's a relatively small and quick update - about 10 mins, it's probably sensible to do it.

Hello,

I have the stock firmware HNav_EU_K0022_2_D1, can I update only the maps?
I don't want to mess with the firmware because I have B&O sound system and some say that can cause problems like with the BOSE system.
Thanks.

 

[JulianHicks]

@SavoE No, I don't think you can do that. If anyone reading knows otherwise, please correct me, but I think the latest maps need the latest firmware.
So you need to go to thread #1 and follow the link to the 4 firmware levels later than yours. I would get all four and install one at a time.
Then install the maps and activator scripts...

 

[JulianHicks]

@SavoE Firstly, I should add that although normally MMI updates supercede each other [that is, you should only need to install the latest MMI update available], you have a very early version of the EU HNAV firmware [K0022] and there was a Audi technical bulletin [TSB] that said that you couldn't go straight to the latest from those early versions.

Accordingly, a stepped approach should overcome any potential issues and as they should only take about 5-10 mins each, it seems worth doing it that way to avoid any risks.

Secondly, I'm not sure anyone has suffered any issues with B&O updates [although I know there were problems with some early Bose updates], but for peace of mind you can cut out any amp updates by doing the following so as to be able to run in "User Defined" mode.

1) For each of the four SD updates that you're going to apply, using Windows Notepad, make the following change to the metainfo2.txt file in the root folder of the SD. [You don't need to change any other metainfo2.txt files on the SD, only the one in the root].

Remove the line "MetafileChecksum=xxxxxxxxxxx"
Replace with two lines
EnableUserDefinedSWDLMode = "true"
skipMetaCRC = "true"

2) Now when you run the update, you'll see two options for update: 'Standard' & 'User Defined'
Choose 'User Defined' and when the list of devices in your car appears, there are two possibilities. The line with your B&O amp type [there are a few different ones and I can't know which one you have] will have Y, S or N against it.
If it's N, it means no update on the SD for this device, so you have nothing to do.
If It's Y or S, you select it and you'll see the subcomponents listed. For each of these look at it and untick any tick boxes. This prevents the updates of that particular component.

Then just run the update and let it reboot and apply the updates for that level of firmware.

Thank you very much for the detailed answer, this is what I was looking for.
But I'm going to try to enable the Green menu with the script and use the User defined option from there. The only question I have is: Is the script going to work for my firmware?

Thanks again.
