Hi There everyone if anyone is purchasing F770 dash cam watch yourself as the front and rear cameras don't record full footage constantly it has a 3 to 5 Second missing area on the footage and the update does not work on your phone's .the camera would be grate if they do a proper update on it until then do not buy .for $1000 Australian dollar stupid camera is useless don't by this unit or any of their units they all nearly run on the same update there's lot of complaints saying it's not working you don't have to just believe me have a look at the reviews and it's pretty hard to get their help as well
