Map updates - MIB3 Discover Media

[GolfRWag]

Just downloaded and updated the Discover Pro in my MY19 R wagon.
Took about 30mins.
Need 7-zip to decompress, which I did to a bigger USB thumbdrive (>30GB) to have room.
That took about 20 mins.

Took 3 tries with the USB, so here's the combo that worked:
*reformat to NTFS
*take MIB1 and MIB2 folders as well as the metainfo2.txt file out of the root folder it is decompressed to on the USB (mine was called P313_N60S5MIBH3_ROW.7z) so the car system can see what it wants.

Plug car into trickle charger as you must leave the ignition on for about 20 mins to do the update.
Then check your state/location and date/time settings on the head unit are all correct after. They were fine.
