Happened to me as well did not seem to matter what I did it carried on for the whole journey of about 40 miles. I left it for 20 mins and it carried on with the problem. Sometimes I saw a fleeting message saying it was too hot. I then left it over night and it has not happened since!!! that was a couple of months ago. THe day was very hot and it had ben parked in the sun all day but I am sure it has been hotter but not had the problem. This was with a mkIV system.

It was wierd but I did have a passenger witness who also tried to press every single button and tried doing anything he could think of with the display. He thought it was hilarious. I will ask the dealer at service time but because it hasn't reoccured I am sure I know his response?

I am pleased to hear someone else with the problem cos I thought I was going mad.
