As with everything to do with VW there is confusion compounded by poor VW web sites and tools. For Sat Nav map updates, I have posted some details previously in other threads ... for the benefit of newer forum members who may not have found these, I suggest you start by reading the following posts ;
The bottom line is that DiscoverCare is a typically bad bit of VW software which is slow, unreliable and doesn't provide the latest map data until much later than the standard download site.
I stand by my previous recommendation to do traditional downloads and update the SD card manually. The advantages of doing it this way are threefold;
- It is quicker than using DiscoverCare
- It can be performed in self-contained steps
- Even if you suffer a power cut during any of the steps, you simply repeat that step before moving on the the next
The steps are;
- Backup the existing VW SD card by copying the data to a PC disk, USB disk or memory stick or 3rd party SD card
- Download the new map data (compressed .7z file) to a storage device, eg one of the above.
- Erase your VW SD card. Quick format the card as FAT32, as this is faster than deleting the files
- Open the downloaded .7z file using 7-Zip and extract the new map data your VW SD card
Remember to slide the tab on the SD card to the unlocked position to allow deleting and writing the data, then put it back to locked when finished.
If you suffer a failure during step 4, repeat step 3 and then 4.
If the card doesn't work after updating, repeat steps 2 to 4.
If the card still doesn't work or you find the new version introduces more new issues than it fixes, and you want to revert to your previous version, simply erase the card and then copy your backup data to the card.
The time taken for the backup, download and extraction will depend on the type and speed of the media used to store the backup and download. A PC or USB disk will be quickest, then a USB memory stick and finally an SD card will probably be slowest.
Now to clarify the situation with the latest map version(s);
V12 has indeed been released (there are 2 realeases each year), but DiscoverCare is probably still lagging behind and will do so for weeks or months. Secondly, even on the standard download web site, some of the bundles are still using the older V11 files, while those that have been updated have a variety of software version numbers (1410, 1420 and 1430) depending on the bundle.
Most of the bundles show a date of 11/7/19 and I believe this uses mm/dd/yy format because 2 of the non-European bundles are dated 6/17/19.
Below is a list of the bundles and their current (as at 30 November 2019) filenames (which include the s/w version). I haven't downloaded all of these to confirm that the file names match up to the data they contain. For anyone interested, the part numbers, s/w version and other details of the data can be found in 'dbinfo.txt' located in 'maps\00\nds\' in the 7z files.
To get to the files, first visit https://webspecial.volkswagen.de/vwinfo ... download#/
and then select the T-Roc model, either pre or post 2019 will do, as you then select Discover Media. If you then hover the mouse pointer over the Download buttons, the file names should be revealed as shown below.
