I heard about the digital dash/'Interactive Driver Display' through this forum, I'd already discounted adding the 360 cam as my dealer advised it was on the list of 'not possible' items, so would have blocked my order. I placed an order a couple of weeks before Christmas.
Regarding the digital dash I've ordered a R-Dynamic HSE (D300), so I sent the dealer an email to ask if I would get it he replied with a PDF copy of my build sheet, pointing out that it was included in the 'bill of materials'. Having said that my order is still in the 'holding pool' status - which according to another post on this forum means its sitting with the dealer until they get allocated more build slots by Jag - so I guess that doesn't mean something could change once the order gets loaded across to the factory! I've made it clear though that I want the car with the digital dash, so I am prepared to walk away if I don't get the spec as I ordered it.
