if there is a way to fold the mirrors, I have not found it yet. I would love if there was a way. Had a Renault Laguna rental this week in France and it did exactly that, car was even locking automatically as you walked away.... I seem to remember that on older BMW models it could have been a dealer programmable function, ie a 2 min job where they would charge you 1r labour
I hope somebody out there as the solution but I checked the manual and was hoping for an i drive setting but no luck
