Well with a little bit of prep and reading here, I finished the base headunit install in about 2 hours. I'm waiting for the cd-changer, XM radio box, and voice control kit to come in the mail later this week.

If anyone's interested I can post install pictures of the boxes and cable routing. With a little poking around I found plenty of space to stash everything up under the dash, and still have easy access to everything for later changes.

Thanks for those who emailed pointers!
