Well, I finally found time to take the dash apart a bit. I'm a little disappointed in what I found out, but not that surprised.

We know that the warning chimes and turn signal noises play through the driver's front speaker. One thing I wanted to find out was if they go through the stereo first, or if the BCM sends signals straight to the speaker. This determines how easy it will be to replace the head unit. Well, it seems they go to the speaker THROUGH the head unit (and/or I would assume through the amp in the Monsoon system). With the head unit disconnected, the warning chimes and turn signal/hazard "clicks" go away. Look for a wiring adaptor to hit the market soon, if it hasn't already.

Another thing I was looking into was the possibility of moving the climate control panel down below a single-DIN aftermarket head unit in order to free up the space where the climate controls normally reside for additional gauges. No can do, at least not without way more fiberglass work than I care to do.

I DID have success with taming the airbag lights though. I'll start another thread on that.

Taking apart the dash is not for the faint-of-heart or those lacking the right tools/experience. The IP trim piece is somewhat of a headache to get loose, especially to the left of the stereo head unit. Once it is loose, the headache isn't over, because you have to unplug all of the switchgear from the backside, and get the shift boot and trim ring free (and free from each other, too) before you can take the IP trim out of the car.

Here are the some pics. If anyone has any questions, fire away. I have a few other pictures I took as well.
