Thank you guys! I am new to Skodas, having just bought a 2017 Octavia L&K. I have spent the last week trying to update my Columbus nav maps. Skoda's portal makes it look simple by missing out vital information (eg FAT32 format, which files to include). The dealer had no-one who knew how, or at least,I couldn't find them! Their solution was a new Skoda Amundsen SD cardI tried another dealer, and they were as bad. The web had lots of info and advice, but most I found was about Amundsen stuff, which I didn't realise (THEN!) works completely differently: from an SD card.
I have learned a lot, and today I managed to get new maps,thanks to you all. One last question - how do you find out whether your system is Mib1 or Mib2?
