My new Superb SE was delivered last week and I'm very pleased.

However...

Before the car was delivered I had the use of a 2011 Octavia with a Bolero. I used a class 10 32gb card no problem, it was instant and very good, had 30gb of music instantly at my finger tips. I put the same SD card in the Suberb's Bolero and it doesn't list a third of the artists.

Anyone had this before, what is the solution?

There are a couple of threads floating around about this, it seems that the latest versions of the Bolero can only read approximately 2000 files from the card. Search in the ICE forum for a more comprehensive answer.
