Hi  I have just bought a octavia 2013 November so mk3 any idea why the radio info screen goes blank every so often then after about 3 mins back up again T.IA

Hiya, good purchase, and welcome! These early screens did suffer from various issues, the fix is to take the car to a main dealer for a firmware update. The latest version seems to have cured most of the problems. The update takes quite a while though, and obviously will cost you a few quid at main dealer prices!

 

Hope this helps, and post up some pics of your new car when you get time!

Assuming you have the Amundsen system, this thread should help you. See the 8th post from aki78.
