change head unit?

Yea, it's pretty easy to do. If you've got the equalizer it won't work, of course. The easiest way to do it is to buy a wiring harness from Crutchfield.com that you connect up to your new radio that lets you plug right into the car harness. That way, all of the wiring is done in a way that won't damage the car in case you want to put the old radio back in AND you're doing it on a bench instead of tryign to wire stuff inside the dash.

I did this on my 90 9000 and it worked great. (in fact, it was a JVC CD player)

I also replaced my head unit. I have a Blaupunkt radio with MiniDisc and used the second DIN slot for an in-dash CD changer. It works great and Crutchfield included the connector that let me plug right into the wiring harness.

You didn't mention what year 9000 you have. I heard that the wiring harness changed for the models with the Harmon-Kardon radio; the Crutchfield part (from what I have heard) only fits 9000's equipped with Clarion radios. I'm not sure that Crutchfield is even aware of this difference and are likely to say that their connector fits all 9000's.

Thanks, Walt. I have a 1997, and the current stereo just says Saab, so I don't know what kind it is.

I think Saab went to Harmon-Kardon radios around 1993. Your 1997 model is likely to have a different connector(s) than the one that works with the Crutchfield part.

The '97 NG900 is Clarion based. I don't know about the 9000 model.
