Except I know they record, don't know much else. Can you help?
Do they need hard-wired into a vehicle or do most/all just plug into a cigarette lighter socket?
Where do you mount the rear facing camera (or is there just a rear facing camera on the windshield camera)?
I see some have GPS. Any benefit to that? I don't need to know where I've been.
Does screen size matter much? Looks like playback can easily be done back to your cell phone or computer.
Are all brands pretty much the same?
What else to know or be aware of?
