I decided to do a little digging around on the trademotion parts catalog. They still don't have the 2011 Camaro, but I found the 2010 Corvette parts.
Parts 2 and 4 are the HUD, and the heads up dimmer switch.
25788254 is the Heads up display
20844868 is the switch
Doubt they would work, but the price is around $300 for both of these on the corvette.
The windshield with the head up display is like $1000 retail and without it is $566 retail.
