3.2. Connect the GSM/GPS external antenna
3.3. Choose the appropriate location for mounting
The ideal location for mounting the device is under the dashboard. However, some types of
coated windshields, as well as windshields with an in-screen heating system can block GPS
signals. External antenna should never be covered by any kind of object or material,
especially not by metal or aluminium. Transmission and reception of GPS signal is however
not hindered by plastic or normal glass. Moreover, put at least 20 cm between the antenna
and a speaker.
