Hi. We own a 2017 Octavia Estate. A few months ago our infotainment system stopped working. It doesn't switch on, so we have no radio or bluetooth, we can't change the time on the clock and we don't have any visual reversing aids (we can though hear the beeps). Our local garage said they couldn't fix it. We took it to our local Skoda garage. Their diagnosis was that there is an internal electrical fault and we require a new unit which can only be obtained from Skoda. We ordered a (very expensive) new unit through that garage a couple of months ago but we have repeatedly been told that it is on back order and they have no idea when they will receive it. Any suggestions about what we can do would be much appreciated. Thanks!
