I had the same problem and it was the power plug was not firm and unstable in the socket. The dash cam was restarting for every bump in the road. I solved it by just making the plug be much firmer. Hope this will solve your problem.
After 1:30 it stops recording at all, no reaction at voice command. I have videos and want to download it at youtube for people to make them not to buy it. I think that it is problem with CPU of this device. Please solve this problem!!!!!
I have the same problem it reboots after 30 minutes or more. I have connected in my home to test it and I power it via my Iphone USB charger.(this I mention that because I dont want to tell me that exist bad connection between lighter charger as the cars moves).
