It worked fine the first ride but on the second all the video was fine until the last part of the journey home. When I stopped there was three lights constantly on the unit and the last files are corrupt. The lights are now stuck on and I can't reset it with the power or the reset button. There is no wifi broadcast and I can't connect via laptop. Can anyone help please? I had one of the first K1 systems and loved it but thought I would upgrade to this.
