Просмотр полной версии : MMI 3GP + SIM US>EU stuck on 2G
Hello,
I have done a conversion for a MMI 3GP with sim from US to EU.
Only two thing still do not work, the tmc does not operate (using an existing EU radio unit).
And the other one is the internat dataconnection is 2G.
The unit is capable of UMTS 3G so it should connect in 3G.
The simcard is a 3G tested it in a telephone.
When i go in the green menu:
/telephony/telephonyumtse3dtrig
All the values are zero.
They should be there:
E2D offset : 11
E3A offset : 8
E1E offset : 15
E1F offset : 15
When i press the set values button, the values are there until i do a reboot.
Then the values are gone and still stuck on 2G data.
Does anyone know what to do to have a 3G connection.
In the EU Units is used a Telit UC864-E Module-AUTO GSM and in the NAR (US) Units it is an Telit UC864-AWS-AUTO. The AWS Version is not able to use UMTS 3G in Europe.
Tschako, Thanks for the info this clarifys alot for me

did not know that either - thanks for sharing the information
these UC864-e-auto are hard to get
I swapped the telit AWS version in my 3GP for a European one (UC864-E) and it operates on UMTS 3G now, speed is much better.
Problem is solved.
Fine! Congratulation! Tell us something about the pricing, if possible...
i have bought one on alibaba, was around 80 euro's.
This was UC864-E with compact form? Which is on small pluggable board?
как сохранить значения в зеленом меню при установке значений они вылетают на 0 опять?
how to save values in the green menu setting they go to 0 again?
With vag can pro you can set the umts values for the eu. There is a zdc file for the telephony gain settings. After that the unit will connect to umts 3g
But you still need a UC864-E mounted in the phone Modul first, to enable the true 3G modes in the EU GSM networks. Isn´t it? The US version has not the EU 3G possibilities.

Its as easy as unplug us one and plug the eu one? No need any coding or something on vagcom? I have an audi a4 with same problem.

It depends your existing GSM Modul! If you have a Telit version, this informations are fit to you. And you have to solder in/out the GSM Modul in the case.
If you have a AH6 GSM Modul, you can plug-n-play change to an EU version of the AH6 or AH3.
Hi.
I have a EU 2011 touareg with rns850 (sim version). In this unit the GSM Modul is the AC75 Cinterion (only edge). I swapped the entire module with a newer AH6 version, but when I turn on the unit, phone doesn't work. In green menu, under "telephony", says "UMTS module installed NO", I know that must be "YES". It's a coding problem or something else??
in efs persist is a file called PhoneModule_AC75 remove it or rename it to i think PhoneModule_Telit
How can i do that? Is there a script? I'm not good in software modification
Someone can help me?:confused: I tried to create a script to look inside "efs-persist".. but didn't work:(
Can anybody write step by step how convert US to EU ?
Can anyone comment on this taken from @theed post as I stuck here:
With vag can pro you can set the umts values for the eu. There is a zdc file for the telephony gain settings. After that the unit will connect to umts 3gAny comment is appreciated, specially concerning zdc file and where to get it as in Vag Can Pro I can´t see any suitable one
There is no VCP ZDC-file or something else, which is able to activate the EU 3G UMTS Modes with an US version of the Telit or AH6 phone modul in the MMI.
The US modules are unable to handle this frequencies and modes in EU. You have to change the phone hardware as descriped in this thread.

Thanks for answer, Yes I undarstand that, just after change modem to eu version (its available at aliexpress) do You need to change smth in navi unit or just update eu firmware and upgrade telit part of it using user defined update or need to change anything with vagcanpro also?
You can restart the firmware update to EU version. It will only update the Telit if it is an older version...

Is it the same situation with Audi A4 B9 2017 MIB2 High NAR? Can't find any information about what lte module is install on NAR cars and how to change NAR LTE freguances on EU.
Thanks for any information!
Yes, totally the same situation. Depending the RF requirements, they use CINTERION Modules in both cases. Bur for NAR it is ALS6A-US and for the EU its ALS6A-EU.
You only can exchange the CINTERION RF Modules into the Harman Housing to bring it from US-EU LTE Modes. Otherwise only 2G works in EU.

I need to change part number 4M0035456 or I am mistaken?
No, the PN you note, is an RF TwoWay-Amplifier to support the SmartPhones in the Cars Hold/Charg Holder.
Nothing todo with the LTE EU-Compatibilty of the MIB Unit.
There is no PN for the embedded RF Module of the MIB units. VW / Audi doen´t support repair issues with parts.
You have to desolder the US Module and resolder an EU version of the Cinterion RF Modules inside. A critical soldering job, I think.
But first of all, you have to find EU versions on the market...

I have found module ALS6A-E. Am I right, that I need only replace my ALS6A-US and it should work properly with LTE?
Price is 57 usd for try, that why I would like to be sure. Thanks!
Yes, it should work perfect in EU! Maybe, it is nessesary to update the FW on the module to support the correct command set in the MIB...
I tried to order such long ago.
Price went from 30$ on inquiry to 150$ and then the guy went away.
If you find it responsive paste a link.

36 USD per 1pc and shipping fee 29 USD to Europe countries, but depends of negotiations, I have ordered 2 pcs for 101 USD with shipping.
I verified the Ali offer you send, but the pictures don´t show the correct case style of ALS6A-E used in the Harman modules.
Normally, Cinterion offers the RF-modules in some differend cases and PinOuts... Hope you´ll receive the correct ones!

On the attached picture, you can see the ALS6A-US placed on the Harman PCB for the MIB

Can I replace only part where it is written ALS6A-E?
Yes, thats exactly whats todo.
But I think, it is not so easy to desolder the both modules away from each PCB and solder on again without damages...
Think you´ll need SMD solder equipment with a pre-heating plate and special hot air pipes todo.

Tschako, thanks a lot for your support and I confirm that changing module on ALS6A-E helps, it works perfectly without any update of FW.
sergey307,
fine, I´m happy for your success!
Hope, the soldering was pretty good todo?
Where did you purchase it from?

Hello, I have a problem with UMTS. I bought mmi 3g + SIM 8R1035746K at auction, it turned out that it is an American unit, but someone has already converted it to the EU. I took out the old module and installed the new UC864-E Telit. After starting up, it still does not see the IMEI, in the green menu there is a phone module installed - no. I ran VCP from ZDC file, the transfer of factory unit from K was successful, but it still doesn't work. Does anyone know anything?
If there was no IMEI readout, the module seems to be defective...
