MMI 3G+ Conversion from MMI 3G(2010-2012) DIY with Component Protection removed.

[infinkc]

Well there are a ton of threads out there, but you need to really read all of them to actually know what you need to buy to do the conversion. I finally had time to get mine installed this weekend so I am putting all the info here in one post that i used to do the conversion.

I have a 2010 S4 with 3G B&O, the MMI 3G goes to the 2012MY.

I purchased the Head unit and Control Panel off Ebay. Cost me around $600 for the parts to do the conversion.

Really like the newer interface, also brings Video over through MMI, Bluetooth Audio without an adapter, and Google Maps.

What you need:
Head Unit 8R1 035 746C (A and B also work, C is just newer, i believe it goes to F now also)

MMI-Controls: 8T0 919 611 C WFX or 8T0 919 611 L WFX (with Start/Stop button) or 8T0 919 611 B WFX (without Start/Stop button)

In other posts a Module 4G0 035 082(HD radio) is what is prefered. My car is a MY10 it had a Radio module 4F0 035 082A(non HD radio), it worked half the time, the volume would mute out and when you try and adjust the volume it would be "Currently Unavailable". Note: you need to have component protection removed for this module also.

There has been mention that if you have the Radio Module 4G0 035 082"G", it will not function correctly for Sirius.
I purchased a 4G0 035 082 without a suffix as that was reported to work well. Had a ton of speaker codes pop up with this unit and audio wouldn't work. Found that the coding had a subwoofer amp turned on (you can also see the subwoofer option in the audio settings). to fix this, change the coding to 0200070(1)0000000001. There was a (2) before. This will fix the speaker errors and play out audio to the amp.
You can Check with a Vagcom Addreess 56-Radio to verify what you have.

GSM Antenna cable. I ordered mine from: (people also just use a generic GSM antenna off ebay with the Fakra connector and mount it by the window instead of using the OEM antenna that is already in the car.)
rfsupplier.com > Custom RF Cable Assembly Wizard:

1 x Coax Type: RG174; Length: 500cm; Connector A: Fakra D Right Angle Jack; Connector B: Fakra D Straight Jack (F03DSJ-F03DRJ-174-500)




Removing the Head Unit, MMI controls, running the Antenna wire are well documented from Richib86

Some Tips and hints that you may run into:

Enable The hidden Menu Via Vagcom
[5F - Information Electr.]
[Adaptation - 10] -> Channel 6 -> Change 0 to 1

To get into the hidden Menu hold the Car and Menu buttons down for 5 seconds.

My unit came out of an A4 so the Splash screen said A4 when powered up.
To change this in the hidden menu:
car/carcodingvehicle
Select No of Screen:
15 --> A4
16 --> A4 Allroad
17 --> S4
18 --> RS4



The car it came out of also didnt have ADS.
To add the ADS menu, just do the portions of this Guide that are in the hidden menu.
http://audienthusiasts.com/VagCom_FL_ADS.html

While you are in the hidden Menu, its a good time to activate the following if you want:
Enable Battery meter
[Hidden menu] [car] [cardevextdevicelist] [Battery] Enable
[Hidden menu] [car] [carmenuoperation] [Battery] Set to 5


I had 2 Faults after the install, they dont affect the unit, but if you want to get rid of them:

03276 - Please Check Software Version Management
http://www.audienthusiasts.com/Appli..._SVMError.html

03157 - Functionality limited due to Communications Disruption
Is due to having an option in the MMI car selection screen that the car does not support, ie: interior lighting. You need to go into the hidden menu and clear out the ones not compatible.

You may get error 03175 and this post shows how to get rid of it
http://www.audizine.com/forum/showth...1#post10353818

You will get Component Protection when swapping the Head unit. To date the only way to get rid of it is to go to the dealer. I was able to figure out how to use a VCP cable to read and write the eeprom from the old to the new. It is partially outlined here: http://audienthusiasts.com/Infotainment_EEPROM.html
I may offer to help do this service but you will need to send me both units. This would save you from the dealer.

[bakedziti]

Great info here! This is on my long list of eventual to-dos as well.

Side note: great placement on your V1 box!

[jsh139]

Really nice! Thanks for the write-up.

Good stuff OP!

The only thing I couldnt get to work was the steering response change when you changed the setting ADS setting (i.e. comfort to dynamic). It seems to always be in comfort. Hopefully your links in your OP will help solve this!!

I know if you try and change it Via the MMI it will not take, you have to do it from the button still. You can do the individual settings. From researching it, it is a limitation of the ADS module since the b8 doesn't have the latest ones, one could retrofit it, but i think its more hassle than its worth.

[JeromeS13]

I did the same conversion right after purchasing my B8. However, I haven't been able to clear the 03157 fault at all. I'm sure it's something super simple that I'm looking over, but I haven't been able to find which setting doesn't correspond to my car...

[14S4GWM]

Nice little write up and conversion.

Were you able to get to Address Word 44 (Steering Assist) through the vag com? I get a "No Response from Controller" error msg. I wonder if this is why i dont get the different steering modes. I dont have the dynamic steering option but it still used to get stiffer when i changed the steering to dynamic.

Nice work. Did you read and write eeprom as per David website or you manage this via OBD?

Tad confused, so you don't have ads, but you activated it on the mmi3g+. Steering is greyed out? How did you control the ads before the mmi retrofit?

Yea done all over OBD, but used the website for the locations of the eeprom to modify :)

My car is a prestige 2010 with sport diff. No adaptive cruise control with dynamic steering. So when i had the older 3G MMI i could change the steering to dynamic and it would get nice had heavy. After the 3G+ conversion, changing the steering to dynamic now does nothing. when i check dynamic steering via VAGCOM i throw a code for having no dynamic steering. I'm hoping i have some setting wrong somewhere.

Are you still able to change the steering to dynamic and feel the difference after the conversion to 3G+?

Sorry cant really help you much, mine works. I say look at the hidden menu and make sure that all the setting match the ADS guide in the first post.


Another + to the mod, is the presets are the first screen to come up, on the 3g you always have to press the mmi button which always bugged me.

[infinkc]

Added some more details to the first post, my speakers cut out pretty often, i swapped the radio unit out since mine was an older unit and there are many discussions that a newer unit is required. Some new coding was need. The radio unit also has component protection! I haven't removed it yet, but audio plays with Media fine(CD, BT, SD), you just dont get radio or sirius.

Why was a GPS antenna cable needed?

[JeromeS13]

Why was a GPS antenna cable needed?

That cable is actually for your connection to the cellular portion of the antenna.

[pierreb]

So a 2010 US Spec car with 3G MMI would need this additional cable?

edit: I understand now. The OEM connector is in the D pillar and I just need this cable to get from there to the new H/U. Correct?

[JeromeS13]

So a 2010 US Spec car with 3G MMI would need this additional cable?

Yes. As Kris specified above, this is the exact walk through from where he converted his 2010 S4

[pierreb]

Sorry yeah, I have an A4 Avant so I wasn't sure if I could just assume it would be there. I'm now googling to see if I can confirm this GSM connector location on my car.

[infinkc]

Why was a GPS antenna cable needed?

Yea sorry, it's not gps, it's GSM.

[pierreb]

For the record, in the avant the spare GSM connector is right underneath the shark fin antenna inside the car. I haven't received my cable yet so I don't know if 5m will be enough.

[pierreb]

I finished mine today. The 5m cable was fine even if I destroyed my fingers routing it to the shark fin antenna connection. The MMI module I got already had the the proper phone upgrade to support AT&T bands so I just had to plug in my ipad's SIM with an adapter and everything worked. Off to the dealer for CP removal.

[pierreb]

Success!

[bakedziti]

What does the dealer charge, approximately, to remove component protection?

[pierreb]

An hr of labor. Mine is $130 shop rate.

[bakedziti]

Thank you! I found a headunit for a great price, so just trying to figure out the final cost. Maybe I'll just pick up the headunit now, and save this for something easy to do this winter.

[pierreb]

If you choose to also replace the radio, you will need cp removed for both so do them at the dealer at the same time. You don't want to pay for 2 visits.

Good point! I have a bad feeling that my local dealer will have no idea what I am talking about though. They aren't overly helpful, and new things seem to put them on the defense, but $100 for the head unit is a steal.

[hiwasss]

@infinkc Thanks for the great write-up, is it possible to get the name of the vendor you purchased the head unit and MMI controls panel from? If it's against the forum's policy please send me a private message.

got it on ebay, LKQ, found their prices to be very reasonable since they are such a large company.

[kyducati]

I'm interested in how you did your radar detector, any info on that?

thanks

I had a thread on it, but the images are not hosted anymore. its actually for sale now http://www.audizine.com/forum/showth...6#post11891216
I modified the v1 display to be completely flat, changed the LEDs, cut the circuit board to fit, cutout the MMI bezel, ran an external cable to the board. Was a ton of work to do, but turned out great.

[hiwasss]

@ infinkc - do you know whether the MMI unit model 8R1 035 746 E should also work?

[JeromeS13]

Same part number, just newer revision.

Try and get a "G" or later. You want to make sure you get one with the updated modem hardware in it so that it supports AT&T SIMs at 3G. otherwise you'll be stuck with T-Mobile 3G or AT&T at 2G.

For model ending in G, would it support T-Mobile also along with AT&T?

[pierreb]

Yes it should. The whole reason for the original gsm modem hardware update inside the mmi head unit was to support the refreshed t-mo 3G bands.

I've gone over Richib86's pics many time and still have trouble making out where the Fakra GSM cable connects to the shark fin. Is it near the rear passenger side or rear driver's side? Anyone has a zoomed out picture would be greatly appreciated.

I believe its the drivers side, but there's a connection on the pass side as well I forget what for. Anyways once you get the rear deck lid removed take off both the side panels and everything will be there.

For a proper step by step of that process i suggest getting a subscription to alldatadiy, or finding a copy of the factory manual.

It's the passenger side, you just pop off the pilar panel and it's in the corner close to the window. I had a pic, need to look for it.
