I had this latest update installed in my 18 Signature a few weeks ago and am very pleased to report that the screen is now activated much more quickly and consistently. :smile2:The latest version is 70.00.335 and was released recently. I took possession of my car last November and it wasn't available at that time. The dealer will do the update free of charge during the first 3 years. It was a little more than 1 hour of labour according to my invoice.
