GPS is not positioned
| Determine whether to use the terminal in areas with poor GPS signals, such as near tall buildings or
underground parking lots
|
Move the vehicle to a location with a good signal Use the terminal
Determine whether the front windshield of the vehicle has metal heat insulation film
affecting the signal reception
| If there is a film, the equipment will be
changed to other vehicles to test whether the blue light is always on, such as in other vehicles without film to test no problem, then the vehicle is caused by the film
Determine whether there is a shield or signal jammer on or
around the car
