Hey guys, I can imagine that this has already been discussed, but I couldn't find anything about it so... here we go.

I have a 2004 grand prix gt2 and it does NOT have the HUD unit, but I'd like to add it seeing as how I had this in my old grand prix and loved it. I want to know what kind of work is involved, or if you can just simply order an aftermarket one that mounts up easy enough.

If you can post links of some(if there are any) it would be greatly appreciated.
