Yeah if it is that new, and you are not super needy for a camera, a reset to 0 with a new unit might be a good idea.
Not all people have the inclination or tools for that matter to attempt something out of the ordinary, and with a brand new unit really that should not be attempted.
I am not at all familiar with the nextbase brand cameras, but are you sure you have the parts properly together, you be amazed on other brand cameras, how many times people have had GPS problems on some cameras, only due to them either not seating the little jack plug properly, or having put it in the AV out jack beside the jack for the GPS.
