Dr Google has not heard of a Nextbit dash cam, so I can only assume that you mean NextBase? Which model?
Fit it behind your rear view mirror, then there is no obstruction. You should not be looking at it whilst driving so it doesn't matter that you cannot see it.
Re wiring. If, as you say, you have no idea on wiring, then get someone who has to do it for you.
The red wire goes to an ignition switched 12V via a fuse piggy back and the black wire goes to a good metal chassis connection.
