Roav A1 Dash Cam

I have updated my A1 to version 2.9 using the roav app. I read on another topic that there was a 3.0 update but 2.9 is the latest update I could get. I also read on the roav site that the A1 had HD. I see no mention of HD on my camera and am curious if this is an error or there will be an update for HD.

I also wonder why the roav app is for smart phone only? Why not have it for the PC as well?

The box on my roav A1 camera does say HD so it isnt an error.
