Wiring of Standard Version
Tips for finding the right wires:
- Use a multimeter to find out the positive and negative sides of the vehicle battery.Note: No matter the ignition key is switched to ON or OFF, the current battery voltage can be shown in the multimeter.
- The way to find ACC wire: Connect multimeter’s black probe to the negative side, and connect the red probe to a random wire, at this moment, the voltage shown in the multimeter is OV; turn the key to ON, if the supply voltage is shown, that’s the correct ACC wire.
- Connect the two connectors together, if the vehicle has no connector, please connect the device’s wires to the corresponding vehicle wires.
Installation recommendation
Please install the device under the guidance of professional personnel.
Note:
- The device should face up to the sky.
- Metal thermal barrier or heating layer, which are always installed on the windshield, may affect the signal, please avoid installing the device under these objects.

Troubleshooting
| Type | Use |
| Unable to connect
to tracking platform |
Check the APN and IP settings.Check whether the data service of the SIM card is enabled.Check the balance of the SIM card. |
| Tracker shows offline | Check whether external power is still connected. Check if the vehicle entered the network blind area. Check the balance of the SIM card. |
| Unable to locate | Make sure the top side facing upward without metallic things shielded.Make sure it’s not in an area with no satellite coverage. |
| Location drift | In areas with poor GNSS signal all building around or basement), drifting may happen. Check whether vibration happens around to trigger the accelerator. |
| No command reply | Make sure the command format is correct. The vehicle may be in-network blind area.Make sure SIM card is well inserted and has * SMS service. |
