- Rear cable must plug into the rear USB port on the front unit.
- 3.5mm jack connection on the rear cable must connect properly.
Note: Please contact us at firstname.lastname@example.org if your rear cam still does not work after confirming cable connection with resolution settings are all correct.
Please meanwhile send us clear pictures which show all the cable connections and order number(ID) for your dash cam. Then we will provide you a solution soon.
Thanks for cooperation.
