Why rear camera cannot be detected?
1. Please confirm whether the rear cable is installed correctly, pay attention to whether the 4pin
connection position is loose and whether the position of the host and the rear camera mouth is
loose. Please try to reconnect.
2. If still not work after reconnection, there may be a problem with the cable. Because when
wiring in the car, it may cause the metal wire in the rubber to bend and cause a short circuit.
Please CONTACT US and we will solve it for you.
Why can't it automatically switch to the rear camera when reversing or why can't the reversing
line appear
1. Check if the 4pin is loose, and if the rear camera port of the dash cam is loose.
2. Check whether the red wire of the rear camera cable is connected to the positive pole of the
reverse light, please do not connect it to the brake light or other.
3. If the connection is correct, please use a tester to measure whether the voltage is output
from the reversing light when in reverse gear.
