Thanks for the reply,
That word cubic (?????) was included in one of the notifications that appeared after I installed We Connect app, but I'm a bit lost with all that. Hope the promised update next week will go ahead and I will see some useful changes made to the IS and fix the unlock on approach problem.
I wonder will the 3.5GB file download only apply to Mk 8's with the updated hardware and software - time will tell, maybe VW will get their act together once and for all and also finally fix the driving errors that have haunted so many Mk 8 owners.
