Just an update. Map has not frozen since June and behaved well (2000+ miles in France).
However, now the radio has frozen.
VW tech at garage saw it and spoke about various issues and how a software update had probably caused them. Or fixed them.
VW know all about this but he says that it will be low down on any list they have. He was sympathetic and it is booked in. He is not optimistic. I asked him about a new unit and he said that the issues were current on new units as well.
Advised me to talk to VW Customer Care. I guess that if they cannot fix it they have to replace it?
I will not accept any compensation (other than (£1700:) as then I may have to stick with a faulty unit.
He said there had been no issues with the basic unit
