Sorry to hear your dash cam isn’t powering on.okay well today its dead /not working , power at the supply cables , ground secure , good battery voltage as the car still runs
is there anything i can do /test please
@Jeff_Vantrue
May I ask if you were using the original car charger to power it?
Could you please try powering the dash cam with a USB cable and a wall charger to see if it turns on?
