When you first start the TomTom GO 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.
In areas where location services do not operate normally, 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, but is not accurate enough to use for route instructions.
