I have been going around to different auto dealers with a friend of mine who is in the market for a new car. So when we go into any GM dealers, while he is talking to salesmen, I just look around at what is on the lot. And I have noticed on a lot of 2006 models such as Impalas, Monte Carlo's, the new 07 SUV's and the Buick Lucerne's, they do not have HUD units on them. Even the most loaded up versions. So, I have not seen anything here on the gminside website(or any other GM websites) about the HUD option being done away with. But has it been discontinued? If it has, that's really a shame. My 04 Grand Prix GTP has it, and I've really got used to it. I especially like the "stealth" mode for night driving. But I guess this would be typical of GM. Just like the night vision aid on Cadillacs, they get rid of an option that is beginning to catch on with other car makers.
