Those of you that have the Gentex mount system, what dash cam have you used that you've mounted to it? I really like having that provision, and I need a dashcam because of all the criminally insane drivers around here, but not sure what the actual mounting style is, if it's an industry standard, or if only a few cameras use it, or what. I suppose I'd have a better idea once I order the mounting arm, but I'd like to go ahead and do it all in one weekend.
