sorry to bother you again, this is the first time I try to update the maps, I downloaded the file, decompressed it and copied everything to a 128gb USB stick formatted in exFat. I inserted the pen drive into the car but nothing happens, according to the skoda instructions I should leave it inserted and it updates itself. but shouldn't I do it manually like the mib3 software update by holding down the menu button? can anyone explain to me how to update the maps? I have a skoda octavia IV 2020 DSG 150cv. Thanks

Post 1 over here I posted all the MIB3 navigation PDFs for the three brands. All the same.

You notice the engine must be running to kick it off then the process can run for a period... like days. I think you can turn the engine off and leave the door open or open it at 15 minute intervals. You may then get it in 40 minutes 🤨. Basically the process uses restore points so if it doesn't finish it rolls backs to a restart point. Use of the car can lead to varying times for it to do it, type of USB etc. If you can do the clear run at it. Although I've suggested the 15 minute x 3 trick and the door open... someone did the door open trick and did it in 40 mins... not a couple of days. So yes my current belief is for mib3 once kicked off the real processing is when the engine is turned off in that 20 min power down, engine on when doing it, it's multiprocessing. Well that's my theory. Clear as mud. VAG just say leave the USB in... and it will only update is there is work to do. Current release on your infotainment system must be < the this release. Currently 24.6.

 

I think people do poke at the menu or see the file picked up. Seat users like a USB with a flashing LED so they can see data activity. There have been issues with USB A to C adapters that are not compatible with data. Probably cheap Chinese imports.

 

You get the MAC issue where you have to use CleanMyDrive since that will fail the signature check. You do also need to place these files carefully in the route directory.

Post 1 qui Ho pubblicato tutti i PDF di navigazione MIB3 per i tre marchi. Tutti uguali.

 

Noti che il motore deve essere acceso per avviarlo, quindi il processo può funzionare per un periodo... come giorni. Penso che tu possa spegnere il motore e lasciare la portiera aperta o aprirla a intervalli di 15 minuti. Potresti quindi ottenerlo in 40 minuti 🤨 . Fondamentalmente il processo utilizza punti di ripristino, quindi se non termina torna a un punto di riavvio. L'uso dell'auto può comportare tempi diversi per farlo, tipo di USB ecc. Se riesci a farlo funzionare. Anche se ho suggerito il trucco di 15 minuti x 3 e la portiera aperta... qualcuno ha fatto il trucco della portiera aperta e l'ha fatto in 40 minuti... non in un paio di giorni. Quindi sì, la mia convinzione attuale è che per mib3 una volta avviato, l'elaborazione reale avviene quando il motore è spento in quei 20 minuti di spegnimento, il motore acceso quando lo si fa, è multiprocessing. Bene, questa è la mia teoria. Chiaro come il fango. VAG dice solo di lasciare la USB inserita... e si aggiornerà solo se c'è del lavoro da fare. La versione corrente del tuo sistema di infotainment deve essere < questa versione. Attualmente 24.6.

 

Penso che le persone frughino nel menu o vedano il file prelevato. Gli utenti di Seat gradiscono una USB con un LED lampeggiante in modo da poter vedere l'attività dei dati. Ci sono stati problemi con gli adattatori USB A-C che non sono compatibili con i dati. Probabilmente importazioni cinesi a basso costo.

 

Si verifica il problema MAC in cui è necessario utilizzare CleanMyDrive poiché ciò non supererà il controllo della firma. È inoltre necessario posizionare attentamente questi file nella directory di routing.

thank you for your reply, then I keep the pen drive inserted in the car without doing anything else hoping that it updates them. currently I have 23.12

Yes that's it, then you have to troubleshoot. That's where the LED activity pen drive come in since they flicker although not everyone uses them and get it to work. Luxury touch.

 

If it doesn't work then the issues fall into

 

- Not presented correctly in the direction structure. One level down in the route etc, has to be at the top, see the PDF.

 

- if using a MAC then CleanMyDrive will be required to remove MAC garbage

 

- no work to be done if the installed release is above the file release (that comes up a few times now with connected services as people try to update but they are ahead of the file release). Installed release is on the infotainment information screen YY.MM and you cross check with MartiniBs designation. If using the Skoda, VW and Seat download web files they may be older than currently installed in the unit.

 

Basically the unit does a signature integrity check on the file presented before setting about the update. If it fails it won't tell you. For mib3 and mib2 high it is impossible to edit, re save or change the contents of the file and to proceed with installation. Why any poking about in the files must be quited and the use of a MAC without CleanMyDrive or similar will lead to issues. The first only the technically minded would do that. On the second MAC users not technically minded fall into that trap but it is flagged up in the VAG pdfs. Old chestnut with MAC users and mib2 high, now carried across to mib3. Having passed the signature integrity check it next looks at, is there work to be done. Current release in the unit verses release presented, if it is an update then it will start the update using rollback restart positions the same as the mib2 high does. That is where it can take a time unless you keep power onto the unit with the ignition off once the update has started, door opened at 15 min intervals or door open... least that is the method I believe will fool it to keep the update going. I've been told the door open method works in a gated community where the update was left running. Took 40 minutes. Normal car use can take several days, depends on what normal is.

Further to that I enquired whether they had the engine on during the door open period, just ignition was the answer. I think you don't need ignition just either the door kept open or open and close it at 15 minute intervals. The last one how I do for mib2 high. Needs someone to experiment, I don't have a Mib3 unit. Just gives it a cleansweep of processing rather than roll back and restart positions.

Hello, I am searching web for almost 3 month now and can't find any leads, I hope someone here can help.

My MIB3 navigation factory database is for EU, My car now is located in NAFRICA region, downloading map updates for new region from skoda update portal is not working as the MIB is waiting for EU region update usb drive, when I changed the Navigation adaptation country to NAFRICA now navigation stuck on loading navigation and I got error DTC on MIB "B126CF1 Navigation Database is missing,"

 

What I found so far is that, there should be a +20 GB file that used firmware update menu "RED ENGINEERING MENU" that we use to update MIB firmware, this file contains the factory navigation map database for my region and after replacing the DB I then can use the offline update files to update.

does anyone here can help to find these files to download them, I only found a VW one for EU region which been used for converted US MIB3 to have EU navigation database, link is here I found from youtube video.

Hope to find any help in that.

If it is like the mib2 high you probably need the navigation FeC altered to the rest of the world or specifically N Africa. I suspect it's an on the bench thing. Have you tried to just update the European maps to see whether it's taking the update. That red menu is back end menu obviously.

 

There will be mib3 enthusiast sites and discussion forums just a question of plugging into them. Saying that as of last year little progress appears to have been made from this thread:

 

https://www.briskoda.net/forums/topic/526371-how-to-unlock-mib-3-preh-with-patch/

 

I'm told thou that on the bench progress is suppose to have been made. Mib3 is better locked down unlike the mib2 high where you could do your own FeC activity. @East_Yorkshire_Retrofits I normally call up for their knowledge. I see they contributed to the thread above. Odis was mentioned, your dealer etc.

Thanks for your reply, Yes My MIB3OI Preh is FEC patched and have FEC of ROW enabled.
and yes it is accepting EU updates because the factory installed nav db is EU so it takes the updates normally.

hope to find a solution for this issue...

The question is whether there are any Github projects. Chillout did most of the running as far as I can see on mib1/2 but I think that's only a place marker on mib3.

I am 100% sure that if the NAV Database file is available somehow like the one I found for EU it will solve the issue, I tried that file on a defected MIB which have southamerica map and when it is flashed with this file the map db converted to EU normally.

All the maps for the whole world were posted previously in this thread and people are using them.

 

 

Well MartiniB top post covers them all and if it's like mib2 high and you have the FeC it should work but then mib3 could work differently. I have seen a person telling someone else on mib3 to change their firmware on a straight map upgrade. EU to EU as if their version of the firmware (on a Seat) wasn't kitted out for offline map update eg. A bug. Given that the firmware between Vag brands is re - purposed it's possible there could be a bug that prevented offline map updates that has been ironed out.

Reckon Chills could be Chillout 😉 the mib guru.

 

The other one is whether the RoW FeC isn't installed correctly or that possible firmware bug about updates... but given it took EU update. Possibly not that then,

FANTASTIC!  Many thanks for that "Link Here" to what looks like the basic maps app and db reinstall package!  I unzipped that file onto a 32GB USB drive, inserted it into the car, did the 5-second MENU press to get to the engineering menu, selected the USB drive to use, and it recognised a Map DB to load.
Took about 15 mins to "verify" the update, and then about another 20mins to install it.  After that the Infotainment console rebooted itself and I know have a working Satnav again!  Maps DB version in System Info showed 21.4.
I've just left the November update USB stick in the car for an hour or so and map db version is now showing 23.12.
Happy days!  I thought my statnav db was dead - since my previous attempt at doing an update the satnav wouldn't start and System Info has been showing blanks for the Nav DB version.
But thanks to you its working like a charm again.
Cheers!

I'm not too sure what that does. @chills if they are Chillout would know. It could be just like a reboot and then took the update.... sort of stating the obvious. Bit like a Windows 11 inplace update as in 23h2 / 24h2 that resets parameters back to the default if they get corrupted. Then mib3 took the update. The question is for N Africa whether that reset had the European navigation FeC in it or in the case of the N Africa question whether the work that was done did actually update the navigation FeCs.

I'm in the UK and it does appear I have UK (plus other places!) maps.  I have noticed that when I start searching for a UK address, loads of foreign place names come up until my search criteria gets specific enough to narrow it down to the UK place I'm looking for.   I've set the region to UK in settings but a Nav search seems to cast its net far and wide until it finds where I'm looking for.

Well it's the whole of Europe that's on the map. The search engine is probably like the Here Maps online search engine so you have to narrow it down a bit. 

 

Free text search is probably the box you are filling in, if like mib2. That there is also a tabular view of the address where people have issues getting the postcode and town names in. The design is really for zip codes where the zone is much broader than our postcodes. It's a mute point whether it uses all 7 / 8 characters of the postcode or less. Bashing the street number will get you to a more exact place if it's been house numbered. 

 

Building names of residential homes aren't in the system, so where house numbers aren't available only the street name comes in. They have centroids of the street so you end up with the centroid (mid point). Postcodes have centroids as well so they get attached to the street. Some house numbering is done synthetically where they know the range of house numbers in a street and stretch these equal distance. Think these files are bought where that occurs or student projects. It fails where a recreation ground for example occurs in the middle of the street. Spacing is wrong. Probably occurs in 5 % of the house numbers.

 

Basically two systems running one on street names and street numbers and one on postcodes. Commercial properties have their own postcodes. Residential ones share. You are always better to get a street number in as well as the street. 

 

People cherish their postcodes... use to do GIS from the start as it was taking off, survey work, analysis, modelling and planning. GIS we got into to assist planning and modelling. Hence my interest in mapping. Census analysis, deprivation and resource allocation... hence the postcode and GIS... two are related 😉. Point mapping is where you scatter the points randomly around the postcode to get intensity. 

 

The early mib3 programmers didn't know how to handle the suite of files they got from Here Maps, you could see they were building a GIS rather than a navigation system. That's been corrected now. They were having you turning off the road into a field to the centroid. The centroid has to be attached to the road so that doesn't happen 🤣. I don't hear about that now.

I have also tried to install this NavDB. My Karoq has N Africa maps preinstalled, but I need EU. But this NavDB doesn't suit me, because my Bolero is Preh, but this DB is for LG. Official update package is not installing

Can you give us the Youtube link to get to the bottom of what it does. The file comes off VAG servers so nothing from elsewhere.

Ok the pdf seems to be the restore if it gets corrupted as it says. Will have a look tomorrow at what file it's pulling up.

Having got my Satnav reloaded and working again (thanks to Romeo26222's post on 6th Feb with a link to the re-install download file), I've also been able to successfully (I think) install the November maps update from the Skoda update portal.

I downloaded and unzipped the file to a USB-C drive, put it in the car's USB-C slot - I didn't do anything else, no tinkering with engineering menu, nothing - and a couple hours later the map database version shown in system info is updated.

 

The blurb on the update portal says it can take a while and suggests to leave the USB stick with the map updates inserted.

My question is, how do I know when its complete? 

There's no progress bar, or "updating" or "updates complete" message anywhere, so how do I know when its finished and its safe to take that USB stick out?  Is it finished as soon as the map version number is updated?

 

Thanks.

Normally there is a parts ID on the file so shouldn't load into a unit that isn't compatible.  You have to study assorted firmware files and uploads to work out what it is. Firmware isn't compatible but whether you'd classify that as firmware needs studying. The maps are interchangeable within a hardware type across brands. The logos get driven by another brand ID check but compatible if it's listed.

 

Need a youngster with mib3 🤣.
