Can ı use Head Up system at on my 93 STS ???

I am not familiar with it. Could you provide a link to the product?

Heads up display system is at deville or sts_v.You can see your speed,or any info on your front window,can ı execute that system to my 93 sts.

I couldnt see after installing this to be worth the hassle. If you happened to find all the parts youd need, it would be hell installing it all. For starters youd need a nice hole in your dash to mount the projector.. For all this information that is projected onto you windshield, I believe it would have to talk to some system on the car. And your's being a 94', I dont see that happening. Damn cadi's and every system talking to every system! Maybe an aftermarket HUD?!?
