I am confused.
I bought a fully loaded 2005 STS about a month ago. For all I can tell, it's fully loaded; I read the manual and didn't see one thing that wasn't included; it's the 4.6L V-8, by the way.
But for the life of me, I can't figure out the HUD. I can SEE the actual lens for it in the back of the car (or I assume that's what it is). It has the DIC control panel; it's missing two buttons, though.
What gives? This car has EVERYTHING else. There literally isn't one feature that it's missing. I can't imagine they put every single option on but one.
Simple if it's missing the two buttons you highlighted, then it does not have the HUD. I too have a 2006 STS4 V8 with everything except the HUD display.:hmm:
