This product worked fine for a few days,but then problems occured. 1. Screen showed only the view from rear cam. No view from back camera, no speed information, no icons and etc. Buttons were not functioning, so I couldn't even restart it. I disconnected it from charger, waited till it turned off, then connected it. It happened several times. Thus problem somehow has been fixed. But 2. Radar sign was always red ( as in photo that I took in garage). Where ever I drive it was always red. No audio assistance happened. I contacted seller and they sent me new firmware that solved these issues. Video recording from both cams and radar detection works fine. But some problems still continue 3. After entering menu camera stops recording and I need to restart device. 4. Can't change recording resolution. After choosing 1080p, I leave internal menu and problem 3 occurs. I restart device, it starts recording, but resolution returns to 1296p.
