I've been using the AP1 version for almost a year now and it's been awesome. The only missing feature is that I wish it recorded when the vehicle is off. The night quality isn't bad, but nothing to write home about either. I love how well it blends in too - youdy never notice it. And yes, it does record audio and auto-lock using g-force sensor in a collision. I'll be getting an AP2 one for my new model S when I upgrade (assuming there isn't a firmware update with dashcam functionality first!)
