It had no adjustment.
I think I'd feel better with a wired camera
heres the one I'm looking at

I figure that I'll just drill a hole between the two licenseplate lights and mount it there. That way it will almost look stock.
As for a screen,
I just bought, as of 5 hours ago a Refurbished Clarion VX400 (most OEM looking as I could find) off ebay for $217 CAD (Thank you auctions!) to which I'll be hooking up a wired camera.
I hadn't really thought about one of those rear view mirror screens. Really, I was in the market for a double din anyways so this all works out - Currently theres a single din pioneer deck installed that isn't hooked up to the steering wheel controls, looks tacky and cheapens the interior.
