Steve,

Does your car have LED rear taillamps?

Also, please post more pictures when you can. Especially interested to see:
-rear seats folded down
-LCD screen display

Have you tried inserting a DVD movie in the nav, with the car in park (try it with Power ON, and in Accessory mode). The movie may play!

When you purchased camry hybrid, did you get any forms to file for tax credit? I thought Dealer will give something, but gave me nothing. How do we file for tax credit?

You file for the tax credit on your tax return on April 2007.

Don't know. It depends on the state/province. In Ontario you fill out a form yourself.
