Thanks for this. I have looked through the thread but Iittle confused. Will I find the firmware update files for MHI2_ER_AU43X_P5406 on there? Thanks

 

Click the link I provided which will take you directly to the post pcbbc mentions. Expand it and you will see all the instruction's and download links you need.

Thank you that helped a lot. Can I ask, if sav wasn’t already activated on the car, will this process activate it? Thanks

Have you removed your VC unit to check which one you have?

 

I have not. It is a 2017 car is this necessary. Will this help determine if the process will activate nav?

 

Would you even need to update the VC on a 2017 car?

 

I’m not sure, all I would like is to activate satnav and carplay.

 

Someone will correct me if I'm wrong here...

The risk of bricking the Virtual Cockpit arises if you have a particular early version of the VC and you try to update the firmware on it. However, in order to activate Carplay and Nav, you likely don't need to update VC firmware at all.
Check VC firmware version:

My VC was H40 0296 and Nav and Carplay work on it.

 

My version is H42 0325 so definitely new enough. I have done the addfec sd card update on the car now which should have activated everything. Carplay now works but nav has not appeared? Any thoughts?

 

The purpose of removing the VC unit is to ascertain whether or not it's a production, demonstration or refurbished unit? This may be why you are having problems? With H42 SW0325 those versions you are pretty much up_to_date, but unless you remove your VC unit, you will not be able to tell which version of those three I stated above you have? It's not that difficult a job, just follow this vid;

TT VC Unit Removal

THEN;
1. Once removed take & post some pics of the labels on the back of your VC.

2. Do you have the basic Audi SAT-NAV?

3. Start your car and press the menu button and TAKE SOME PICS's!

4. Have you used the MIB tool?

5. Can you access the green menu's shown by Bob?

6. Look in the Knowledge base thread, there's a ton of info in there!

7. TAKE AND POST SOME PIC'S!!!

 

You need to do the coding in this link:

Then install maps as per the fixitfallows video.

 

Thanks for this. I added the necessary fec codes for nav and then did the 2025 map update. However navigation did not appear, have I missed something?

 

Have you done the coding using VCDS or some other method via the OBD port?

 

I have an OBDeleven pro but I didn’t know I needed to do this to activate nav as it’s not mentioned in the youtube tutorial? If this is necessary, could you point me in the direction of a guide please, thank you!

 

Fixitfallows already has Nav so doesn't need to code it.

I think for OBDeleven:
Unit 17 is called Dash Board
Unit 5F is called Infotainment.
You should be able to sort the long coding now. Also worth doing the TMC.

 

Thank you. Are there any instructions anywhere for how to do the long coding? What is TMC sorry?

 

I understood the More Incredible Bash update would enable navigation. These screen shots and instructions are taken from the 718 forum posted by MIB Wiki

• Enter GEM
• Find the following screens in GEM and run:
  • flash patched image...
  • Enable EU navigation

 

Well, something has to do some coding. That's really cool if MIB can do that!

 

@Barmybob - You may be entirely correct - but the Porsche has a centre screen which I assume connects only to the MIB unit - so that may make a difference here.

To activate Nav on a TT, Unit 17 (Virtual Cockpit) has to be coded.
In fact, I strongly suspect on cars with - 7UH Preparation for navigation system (MIB) - on the build sticker, coding the VC and installing the maps are the only things actually required. Worth checking the red menu to see what Adaption keys are already present! Most likely the fec for maps will be there but will have limited the car to three years of maps from new - so new maps won't be accepted until the map fec is updated.

 

@Barmybob - You may be entirely correct - but the Porsche has a centre screen which I assume connects only to the MIB unit - so that may make a difference here.

I have only run the update on my car, a car that already had maps from factory so I am not sure.

The Porsche has the same MH12 that the TT has, and it uses the exact same M I B software hack, just different patches, and different screen, but it should all be the same. The Porsche guys also used to use the usb/ethernet putty method.

The chap I linked to on the Porsche forum appears to be the chap behind MIB - Android Auto / Nav etc... Do-It-Yourself-Thread | Page 2 | Porsche 718 Forum

As my car had Nav I only needed to run the patch so didn't go looking for ENABLE.

 

Hi, I have done this with no luck. Any thoughts?

 

Do you mean you Enabled EU Navigation in the Green Menu?

 

 

Although it displays this, navigation is still not active.

 

I also believe that this is the fec code for navigating and my car is saying it is activated.

 

I suspected this might happen. Go back to #15 above. I think the green menu thing can only work when the car has a centre screen. Nav must be enabled by coding on the virtual cockpit.

 

Hi, thank you for the reply. I feel like a bit of a noob here, is there anyway you could explain exactly what this means I need to do? As in what does Bit 6 = 1 mean etc? Sorry about this! Thanks

 

Hi! I have fixed it. Thank you for your help everyone, I now have everything activated. For reference if anyone is in the same situation, follow the youtube tutorial by fixit and then if nav doesn’t activate, on the OBDeleven (has to be pro for coding), go to Unit 17, press long coding and there is a toggle to activate navigation! Simple as!
