When I first had the camera I had the same issues, even a new motorcycle battery and a Fuzeblock didn't fix the issue, in the end some EMI supressors on each of the four USB connections into the recording unit got it working. The problems are back again, really quite fed up with this unit given what it cost me. Here are two videos showing the problems I'm getting at startup. Has anyone here got a unit that works consitently without having to take the battery out or factory reset every week? https://www.youtube.com/watch?v=QMa7JKqbhYU https://www.youtube.com/watch?v=zXLibfsaHOo After a few hours tinkering in the garage it would seem the rear facing camera is dead/causing the problems. Raised a support ticket but not heard back yet.
