MMI 3G Conversion from US to EU – How to do it?

We are receiving quite a lot enquires how to make a full conversion from US mmi 3g to EU.

To do a full conversion from US to EU it’s a bit complicated, and not everyone can do it on their own.

To make full conversion, we need to start with changing language in EEPROM.

A bit more informations about EEPROM, you can find here! (click here).

Basically US cars has information only about:

• US english
• Spanish – US version (a bit different than in Europe, only in firmware code).

where EU cars might have informations about all European languages except above

If you decide only reinstall firmware from Europe version on US version you will do that… but, you will don’t see any types of font / words on mmi screen, as it has coded only US languages, not Europeans.

So, to install EU firmware on US cars, EEPROM language section has to be modified.

But..

There’s another way to install Europe maps on US cars without changing language in EEPROM – but you will stay with US english language.

You will need to install latest US firmware. Installation procedure we describe HERE, there’s nothing else to do. If you have bose system, you will need unselect it for update (described in tutorial).

Full conversion packs:

• Audi MMI 3G High – Hnav US to EU Conversion pack.
• Audi MMI 3GP HN+ US to EU Conversion pack.
• Audi MMI 3GP HN+R US to EU Conversion pack.

After successfully firmware upgrade, you will need to enable Hidden green menu (how to do it, described here).

In Green menu, you have to go to the: SWDL, and enable:

• User defined mode.
• Ignore region and variant.

After that we need to change the region. So in Hidden Green Menu go to the: System > Internal

and select there Rest of the world

Then go to the: Nav -> databaseupdate And Change your “Active HDD Nav DB” to the region/country of your choice in our case: EU.

List of regions:

1. Unknown
2. Default
3. EU
4. North America
5. South America
6. AGCC
7. Korea
8. Japan
9. China
10. Asia Pacific
11. South Africa
12. Australia (New Zealand)
13. India
14. Taiwan (ROC)
15. AGCC_2 (arabic)
16. Turkey
17. Chile
18. no navi db

After that, you can perform with maps update using our tutorial, click here to get there.

Full conversion packs:

• Audi MMI 3G High – Hnav US to EU Conversion pack.
• Audi MMI 3GP HN+ US to EU Conversion pack.
• Audi MMI 3GP HN+R US to EU Conversion pack.

Please remember to remove old nav database and nav partition (everything is described in tutorials).

There will be one more thing to do, change radio frequencies to work with EU. To do this you can use OBDeleven, just find and click option to modify radio frequencies.

I hope this tutorial will help you with US conversion. IF any questions just ask in comment 🙂
