device to interfere with GPS reception. The following places are suggested for installation:
Figure 7 installation place suggested
Under the dash board below the front windshield;
- In the parcel shelf in the rear;
- In the front bumper( non-material face), please ensure the device cannot get wet;
- Under the wiper version (non-metal), please ensure the device cannot get wet.
Notice: If the windshield is pasted with metal thermal-protective coating, it may affect the
performance of the device. In this case, please change the installation place after consulting the
professional.
