PBKid talked me through it a few months ago. He is a pro installer at Best Buy. Here are his instructions:

as far as taking apart the dash-
1. take off the little piece around the changer/cigarette lighter (it just unclips with a good pull)
2. take out 7 screws to remove dash; one above the stock head unit, two above the steering wheel, four along the joint of the dash and the knee bolster (place below dash)
3. pull dash out, but be careful not to break it trying to get it past the wheel (that is the hardest part on the VX
4. unplug all the plugs so that you can completely remove the factory dash
5. before you do any of this pre-wire the harness. its really easy to do, strip all the wires on both the JVC radio and the aftermarket harness...then either solder or use 'butt' connectors to attach them to each other. (you may be able to pay the best buy guy like $20 to pre-wire it up for you really quick if you dont have all the tools to do it) but if you can get a hold of all the tools its just a straight match, color to color. you will need strippers, butt connectors, and crimpers to do the wiring
6. next plug in the harness to the factory harness and plug the other end into the JVC...mount the new radio (you should be able to remove the factory brackets off the factory radio and put the brackets right onto the JVC making for easy mounting) and make sure everything is plugged back in when you screw the dash back in...
7. there's a basic breakdown of the install for ya...

I had everything done in about 20 minutes.
