Tarraco specific SD card upgrade steps:
1. Safely remove the SD card from the
Tarraco (Menu > Setup > Safely Remove)
2. Go to
https://webspecial.volkswagen.de/vwinfo ... s-download#/ and select:
Car: Tiguan All Space (From 2019)
Unit: Discover Media
3. Download the map pack (Europe 1 at 13GB is the one I went for and will fit on the V7 SD card, and likely other versions)
4. The file you download is a .7z file,
how to unzip depends on the operating system:
Mac: Use The Unarchiver (Free on Mac App
Store)
Windows: Use 7-zip free download from
https://www.7-zip.org
5. Copy the contents of the SD card taken from the
Tarraco to your PC, it should have a folder called maps with several folders underneath it.
6. Make a second copy of a single file on the SD card, called OVERALL.NDS (it's in /maps/EEC/EEC_WLD/OVERALL.NDS) and keep this handy
7. Delete (don't format) the contents of the SD card
8. Unzip the 7Z file contents onto your PC/Mac
9. In the newly unzipped download maps folder, locate the OVERALL.NDS and overwrite it with the one you saved from the car's SD card in step 6 above
10. Copy the new maps folder (containing the new maps files and your old OVERALL.NDS) back onto the now empty SD card
11. Back in the
Tarraco, reboot the unit without the card inserted by holding down the volume until the SEAT logo appears
12. Once rebooted, ignition back off and insert SD card, and enjoy!
A few points to note:
The SD card itself is tied to the vehicle, so you have to overwrite the files on the existing SD card not just buy a new card and write to that, otherwise the car won't accept the card.
Also make sure you back up the full maps folder from the card when you first put it in your PC/Mac in case anything goes wrong, you can simply put it back on the card and revert back to the original maps.
