Did any first Generation SRX have a factory Heads up Display? It sounds like at least the Cadillac STS had one? Would it be possible to "retro" fit a first Gen SRX with the STS unit or a more compatible one? Or is it a way too involved/complicated procedure? Impossible? I have never understood why Heads-up Displays never gained more popularity. My Pontiac Grand Prix Turbo has one. I miss it on my other cars. Especially the ones that don't have digital speedometers, just analog ones.
