Your VIO first uses locations services on your phone to quickly find your location, then uses your VIO device to find and track your location. If location services on your phone are off then only your VIO device is used to find your location and it may need about 30 seconds to show your current location on the map.
To ensure good satellite reception, use your VIO device outdoors and keep it upright. Large objects such as tall buildings can sometimes interfere with reception.
In areas where location services will not operate normally, such as tunnels, your location may not be accurate.
Important: Your VIO cannot give you route instructions until it has received location data.
If your device has no GPS reception, the 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.
