I'm a Goggles 2 user with either O3 and old Vista/Air Unit. I must point out the absence of the 'advanced camera settings' menu within the menus of the new Goggles 2 when used with the old air unit/vista.
As a consequence there is no setting for auto recording at arm on the Goggles.
I would also like to point out the absence of the possibility to choose whether to record the osd in the goggles' dvr.
