HD on the rear screen wont make any difference with tint, I like the compactness with no LCD screen. Used to have 2 separate cams with screens and it is to distracting IMOInteresting thread guys. Just some additional information, I'm not sure when they'll be released, but he 750's are up on the website.
BlackVue - Full HD 1080p Dash Cameras with GPS
The 750 offers full HD on the rear camera and the LCD screen. No idea on the cost...but judging from the rear-camera (night time) video they have posted, and the assumed increased price, I don't think it's worth it over the 650?
Anyway, the 650 looks great, I'm looking into this now because a dashcam is useful on road, but I would like to get footage of my offroad adventures as well, and a GoPro just isn't as good it seems.
I also REALLY like the way you guys are running the wires and just plugging the 12v into the center console. Great location, as I wouldn't want to hardwire, and I don't use that plug anyway!
For additional information, the blackbox mycar seems to have a lot of very useful info:
