Thanks for the response. Can confirm that I followed all steps as listed above, so only copied over the overall.nds file, didn't format the card and instead just deleted and re-copied new files, didn't use Windows 11 as have Windows 10.Step 9. of the workaround people inthe past copy all files over rather than just that individual file. Possible not your case.
Advised not to reformat these cards. The cluster size should be 4096 and Fat32. In the past people reformat, get that wrong so it won't read the card in the unit. Some versions of Windows have been known to corrupt the CID part of the card. Early versions of Windows 11 where the cluster size got changed in the reformat. You just need to highlight the files and delete.
Attached is the VW manual on the file processing but you do need the workaround file copy. It won't work without. This just frigs the mapcare which was included with VW and Skoda but not Seat. Never sold in the UK hence the workaround.
Left side slot should be used for the map card.
Workaround
Using a PC or a MAC ?
PC: 7 Zip is the preferred VW tool, other unzip tool including those built into Windows, can cause difficulties.
7 zip can be obtained from
https://www.7-zip.org/download.html
MAC: VW instructions
"ATTENTION
If the map update is performed using the Apple® OS X operating system you may find that
Discover Media does not recognise the map material or displays it incorrectly. This is due to
a lack of compatibility between the “7 zip” program and the OS-X operating system. In
addition, the OS-X operating system has a tendency to create hidden additional files on
external data media. We therefore recommend that OS X users use the “Keka” unzipping
program. We also recommend using the “CleanMyDrive” program to remove any hidden files."
If a MAC is used CleanMyDrive is run against the SD card after the maps are copied across to the SD card.
Having identified which unzipping tool is required and special Mac SD card cleaning required... free to proceed.
Steps:
- Download the latest standard MIB2 maps
- on the infotainment go to settings, safely remove, sd1 card
- remove sd1 card from glove box slot
- long press on the on / off to reboot it a couple of times
- insert sd card in to computer
- copy and paste all contents to a directory on your computer
- Format the SD card keep it as fat32 and leave format settings as default in file explorer (don't forget to push the card lock mechanism to off) (ditto in a MAC or delete all from the SD card)
- Copy the new downloaded map version to the SD card (after unzipping it)
- Replace /maps/EEC/EEC_WLD/OVERALL.NDS on the SD CARD with the one from the original SD card
- eject the sd card (on a MAC run CleanMyDrive on the SD card - then eject)
- Inserted the card into the card 1 slot in glove box whilst infotainment is off
- power on and go to navigation
The unit should then boot up into navigation. Note it does take a little longer first time round. If it refuses to boot up, press the volume button forcing a reboot, hold down until the unit reboots. If this fails it will be issues on the overall.nds file / copy issues. Revisit the process. Failing this restore the back up.
‐----
The other possibility is someone has let rip with the unit with the mib2 standard toolkit and made a hash of the FeCs in the unit. By far the easiest is to use the workaround to update the maps not get into technically modding the unit.
I'll have another go at copying the map files and the V1 overall.nds file. To confirm, are these the only files that should be on the SD, just the maps folder and files included and then the overall.nds file in the specified directory? Or should the root directory contain anything else in addition to maps?
Thanks.
