I have a DDPai Mini3 1600P in my 2018 Volt. The DDPai mini is a fantastic dash cam for the money. I like to keep these as out of view as possible. I mounted mine above the left side of the rearview mirror, just below the headliner. The only negative is that the plastic enclosure behind the rearview mirror does block a small portion in the lower right of the image. The blockage is small enough that I think that it's worth it to have it completely out of view while driving.
That's my 2012 Volt getting some charger time in the garage.
