hello. I just bougt a 2013 Superb II facelift. I believe it has a Columbus. might be wrong. the Skoda is an elegance version and it has satnav built in. the SW version is 5238. the stereo freeze every time I turn the engine on. only on/off button works, no sound and nothing happens when I press touch and regular buttons. sometimes hard restart helps, sometimes it has to be done several times, sometimes doesnt help at all. I  have noticed that other drivers had same problem on this forum, however I couldnt find a way to get a firmare to try sort the problem. can anyone provide a link with latest firmawre but better if the original firmware and some clear instructions. I dont care about versions, satnav or how it looks, all I need is Radio, media, and optical reversing system is not bad either, or at least radio to play. thank you.

I sent you link to download SW on PM

Thank you. Why is it called testmode?
