As others have noted in order to get the speed limit signs and lane keeping assist information displayed in the Head Up Display (HUD) you need the Driver Assistance Package (DAP).

Without DAP you get the current speed of travel displayed and you should also be able to display navigation information such as distance to the next turn and which lane to move to for a freeway exit or interchange.

I have DAP in my car which includes adaptive cruise control and when I am setting the cruise control speed, the set speed temporarily shows in the HUD as I make changes. I'm don't know if this only happens with adaptive cruise control or if it also happens with the regular cruise control.

I'm not sure if I would have ordered the HUD if it was a standalone option and not part of the Prestige package. However, now that I have been using it for two months, I find that I hardly ever look at the virtual cockpit since all of the information that I need to see while driving is shown on the HUD.

I like the HUD and find it a lot more useful than I thought I would. Its hard to go back to driving my other car which does not have a HUD.

I have a Prestige with DAP, and the HUD not only shows my speed, lane assist, and speed limit but also shows nav turn guidance and nav lane guidance when the MMI Nav is active.
