The Optima K5 is a fully imported model from Korea. Normally, all units which are imported or even semi knocked down (S-KD) basis do not come with the wide screen touch screen /DVD player/ built-in GPS unit.

The reason being, (in my assumption) is that when Naza introduce such an item, it must be able to respond to any frequent repair, replacement or warranty within reasonable time frame and the only way to do that is when they do their own sourcing instead of relying for stocks from Korea. Maybe it is also due to cost factor and the need for local customization i.e GPS licence which require a certain level of control.
