common problem:
Question:
Time reset, no memory function
Answer:
This problem is caused by incorrectly connecting the power cord. The yellow wire of the power cord needs to be connected to the positive 12V+ of the car battery (this will give the device a continuous power supply and keep the settings and time memory function). It is recommended to check the red and black lines of the power cord. The red wire of the power cord needs to be connected to the car ACC12V + ignition switch, this correct connection will make the device shut down together when the car is turned off. The black wire of the power cord needs to be connected to the negative pole of the car battery 12v-. If it is the first installation, you only need to connect the red, yellow and black power cords to turn on the device and test it.
