I have exactly the same problem! It started after just one week with my brand new Viofo A119S.
Connecting the camera directly isn't a option, because the connector is on the other side of the camera (I put all the wires away).
My seller replied the following to me (which I'm very unsatisfied with):
"Viofo advised that replacing the GPS mount will not solve the issue since there is a problem with the chip that connects to the GPS mount, they have therefore released a new chip and GPS mount that should solve the problems when replaced."
I opened a ticket for this same issue for BOTH of my A119's. The constant chime over and over again is driving me nuts. Poor design me thinks. Powering directly means removing all the hidden wire and routing it to the other side of the camera. Not happy at all. And how would the GPS work when it's no longer powered once I plug into the camera directly, Captureyouraction?
I have just started to get this issue after less than two weeks. Connecting direct in the house via USB supply results in the same issue so not convinced it is anything to do with the GPS unit.
I have same problem on my A119 - keeps restarting during drive. Bought less than a month ago!
I really don't want to connect the cable directly to it - will make the cable more visible and make it more annoying to remove the camera in order to download movies.
Any one found good solution for that? What if I'll put a small sponge between the camera and the GPS so it will be tighter? Anyone tried that?

We suggest you format the card using the GUIFORMAT tool if you use Windows.
You can download this tool from below link:
If the issue still occurs after formatting, could you please try another card?
According to our experience, Transcend or Samsung Micro SD card works well with our camera.
Is it possible for you to try one of such two cards, or borrow one for a try?
Also please use the original car charger.
