Don't know whether I should be worried or not, but when I started my car this morning (Superb Elegance wagon) I noticed that the steering controls for the Columbus was not working. But Columbus itself was working and I could listen to music. After approximately 10 minutes however, the music stopped and the screen had frozen. Couldn't turn the system on or off. Using maxidot, I noticed the GPS had also stopped working.

Turning the car off and on again quickly while stopped in traffic didn't resolve the issue. After stopping for lunch, it all came good when I started the car two hours later and is working fine.

Fingers crossed it's nothing but anyone else experienced something similar?
