Use the multimeter connection method to connect the wiring of the car navigation system in series between the battery and the negative cable. Before connecting the car navigation system in series, you need to set up the multimeter properly. First, select the type. Then choose the probe positions, with the black probe always placed in the COM position. Connect the red probe to the negative cable of the battery and secure it firmly. Loosen the negative cable screw, connect the black probe to the battery terminal, and then slowly remove the negative cable.
