I'll be interested to hear how you get on with the new camera, I also am looking for one and ideally would go with the 2.0 from BMW but it seems to be delayed again and again...The original I had heard about the formatting issue of the SD card requirement every 3 weeks or so and the large size, shiny appearance and lights had stopped me from using it.
I started a thread a while back about dash cams for the G series 7's and there were a few replies and alternatives, a bit late now as you've gone forward with this one but I'll hope you'll come back with info and thoughts on it.
Safe travels.
