Hey all...first post just signed up as I'm shopping for a 2015. Ran into the same problem (aside from the paint colors availability which I found out in another thread is due to manufacturing shortage).
The order page at the dealer gives "not in this allocation" errors when you try to add the Rear DVD to a build with the Laguna/Sepia seats. It's all that's holding me off from placing the order on a Billet Silver model. iPads would work but I really love the implementation of the factory system so I don't want to compromise and then be unhappy down the road.
I'm having a local dealer check every few days to see if the option enables...does anyone have an inside line on when this might be available otherwise?
