Yes, it’s part of the advaced pack.
However, had my brain been working when I added the pack I would have realised that you can just pre-heat the car before you leave using the Skoda App and that shifts the ice on the windows as well, did it tonight as my daughter is here and wanted a Chinese. Set Air-Con to 20c for about 15mins, got in, no ice and nice and warm so off we went.
Been busy going over sound settings with a very helpful chap on the Facebook forum, so far it looks like the Subwoofer either isn’t fitted (polystyrene cover box is there in the boot well), it isn’t connected or it’s duff. Both got the same test music so just waiting for him to run another test to confirm it.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
