Review on WOLFBOX G850: The Ultimate 4K Mirror Dash Cam With Dual Cameras, Night Vision, Parking Assistance, And GPS by Phil Show

This rear-view camera system worked well out of the box to replace another that had lost it's monitor signal. I find that the time is always set to another time zone and after changing it to our time zone - followed by turning it off in the garage, it reverts to the original and needs re-set each time. That is a bit frustrating. The speed from the GPS is exactly the same as my Garmin Nuvi and both are off a bit from the speedometer in my Subaru Outback. I trust the Garmin and this system more than the Subi speedometer. Good video - a bit blurry at night until I turn down the brightness - and then it is fine. I would purchase this again if necessary.
