  • Check whether the SIM car has password or not.

  • Check if the SIM card is inserted properly.

  • If the vehicle is parked in a place where the GSM signal is weak.

  • GSM base station of mobile operator is crashing.

  • Whether this SIM card is suspended (such as forget to pay the bill…)

Q: Why GPS can not calculate the position?
  • Do not park your vehicle under shielding or under a building.

  • Make sure there is not be any metal shield, such as windshield heat insulation paper with metallic content, above the GPS antenna - which may block the reception of GPS signal.

  • Check whether GPS LED is dark or not. If it is, please restart GPS-911.

Q: Why does GPS positioning take such a long time?


The time used for positioning is affected by many factors, such as the weather, distribution of clouds, roadside trees, elevated roads, nearby high buildings, heat insulating papers containing metal elements, and even the covering of the hands, may affect the reception effect of satellite signals. Positioning a vehicle in an idle state takes less time than positioning it in motion state.

  • Adjust the volume of the speaker

  • Check if the signal line of the speaker is correctly connected, or becomes loose.

  • Out of battery.

  • Park button is off.

  • A car is moved within a restricted area.
