Gps Reception - TomTom BRIDGE Reference Manual

GPS reception

When you first start the navigation app, it may need a few minutes to find your GPS position and
show your current location on the map. Make sure you have GPS activated on your device.
Tip: The GPS settings are in the device's Settings app.
In areas where GPS reception is not possible, such as tunnels, your location may not be accurate.
Important: The navigation app cannot give you route instructions until it has received location data.
Some devices need a data connection to obtain a GPS location.
If your device has no GPS reception, the navigation app uses positioning information from Wi-Fi
networks or mobile phone towers. This information is used for route planning and to determine your
approximate location.
