I have a Blackvue DR400G-HD II new in box I'm about to put up on ebay (I already have an ITB installed in my FX). If you're interested shoot me a PM and I'll cut you a killer deal:

Also, if anybody else is interested in a dash cam, I can pretty much get any model at a really good price with 3 day shipping. I used to work for a BIG Korean company and have several Korean contacts.
These cameras all come from Korea, where they have major insurance fraud and hit and run problems - hence the development. PM me if you are interested.
I will post pics of my install later today, I have it mounted behind the rear view mirror as well. There is a very convenient way to route all the wiring and doesn't require anything more than ONE panel removal. Its pretty slick.
