this link here is old. there is a new version from 11.2014. next version is coming in 06.2015.
every car with a new generation nav system gets free updates for 3 years.
for the columbus 2, you need an any big enough SDHC card.
for the amundsen 2, you need the original SD-card that came with the car.
this has been posted here many times and is fully official. just open your eyes or ask your dealer.
Thank you for sharing.
I'm now coping with an Amundsen+, but it doesn't seem to come with 2 SD card slots.
In case I find the second one, do you think using a normal 32 Gb SD card with downloaded maps will be enough for the system to work properly?
Or do I need any kind of magic code by Skoda?
