HUD Retrofit
 

Is it possible to retrofit a HUD (Head up display) on a 2005 STS AWD with 1SG package? I figure the car should already be pretty much wired for it and just the HUD projector need to be hooked up and a side switch replaced.
I saw some posts about HUD retrofits on a Corvette forum. Should be the same HUD as the Caddilac uses, right?
