I just recently installed my avic f700bt and love it. Ran my navigation antenna underneath the carpet, into the trunk, then out so it sits a few inches to the right of the wiper blade mount on the rear glass. The usb/ipod cable is just routed into the glove box.
$350 is the cheapest I've seen yet. I paid $400 for mine about 1 month ago and a week later saw it at Best Buy for over $800. I would've rather got the 900 but for the price the 700 was just too good to pass on.

avic411 is a great site for info and hacks.
