SW03ES:
Thank you! I'll be happy to do a better writeup when I get a chance.

The installation is easier than you think. It's just a matter of patience and initiative. I'll be disassembling my car in the next few months to add the camera and mic as well as rear seat audio from a Sienna. If you plan on driving up to the Sacramento area in the future, let me know, and I can teach you. It's really easy.
I can post more detailed instructions on trim removal, tools, and techniques when I get a chance. The best trim removal tool I've used is a thin and flat screwdriver covered with blue 3M paint from Home Depot's paint dept. Just make sure to check and change the tip tape often.
Cutter:
As far as the factory manual, I bought mine on eBay which is on a CD. It's in pdf format, but it's missing an index. Not too bad for $10.00.
