Received my Blackvue Wi-Fi today. It's similar to the DR400G-HD II but it's a little bigger, has ventilation slots, and uses Wi-Fi to connect to a smartphone to access the video.
Also took the opportunity to pick up the Power Magic Pro as I intend to wire this up full-time rather than only at ignition. Will put it on the car tomorrow and provide some video sample and impressions.
I didn't expect to receive it this quickly, but I guess they started shipping a few days ago. Expect the 400 to drop in price now that this is out.
Pictures installed and video of driving/parking are in
