MY15 Head up display?

I notice the MY15 is now showing HUD as a feature (depending on model)

Has anyone seen this yet... are there any videos around showing it in action?

There's a video on the web showing it on a Discovery, don't ask me where to find it

So, the toy-stacking begins. I had a HUD on my C6 Corvette, and admittedly, if you are driving fast -- especially at night -- it's nice not to have to take your eyes off the road. But it's really only useful if it projects your nav. And on an Evoque? Remembering it was designed for a fighter jet? (Although the ones for use on a motorcycle seem like a good idea).
