I have mine set at 720 - 50 - medium, as it gives me 3 hours 22 mins of record time, compared to 2 hours 15 mins in 1080, to be honest, watching it back on the pc I can't see much difference. I have the suction cup mount, which I position inside the screen, this seems to stop most of the wind noise, when using the skeleton back door.If you use the solid door the sound is a bit muffled. Also fitted a usb charging point in the dash, as the battery life is pretty poor, even with the bacpac, you can now get a skeleton housing, so you can charge on the go, but I use the bacpac and pass through charging. I've only tried time lapse in the car once, and used 2 second intervals, which I think is too long
One other tip I found, was to use a satnav mount to make a suction cup, It's a couple of £ as opposed to 30£
