my mission is to make onstar work in my 01 DHS.

heres what I need to know.

does anyone have onstar wiring diagrams for my 01, and for a 03 or 04?

the 04's are upgradable, but my 01 isnt. my 01 aurora 3.5 though is upgradable. if I can manage to get a upgradable unit into my car, the folks at the local cadillac dealership will use the vin off the donor car to get me upgraded.

I know its not a cost effective idea to do this, but according to the wifey, either get onstar working, or a new car.

Thanks Guys!

Lots and lots of threads and posts on this problem down in Cadillac Technical, Electrical and Audio/Security.

OnStar is an incredibly expensive way to have hands-free cell phone operation, so the BlueStar conversion makes a lot of sense.

If that won't fly, you're gonna be in the market for a Cobalt real soon.

Um, yeah that ^^^ -- and carries a testicle lockbox...

Why not just get a used 03/04/05 Deville of some flavor that has upgradable or full digital, and not worry about the conversion? You should be able to find one cheaper than a P.O.S. Cobalt...

I had the "update conversion" done on my 02 STS and it all works better than the original setup. It's still a darn expensive cell phone............I need some more minutes.

You'll notice that the conversion antennae on the 02+ OnStar vehicles have the loading coil closer to the mounting base instead of up in the middle of the little whip.
