My device will not acquire GPS signals
If the device is not acquiring satellite signals, there could be a few causes. If the device has moved a large distance since the last time it has acquired satellites or has been turned off for longer than a few weeks or months, the device may not be able to acquire the satellites correctly.
- Ensure the device is using the latest software. If not, update the device software (Updating the Device Software).
- Make sure the device has a clear view of the sky so the antenna can receive the GPS signal. If it is mounted inside of a cabin, it should be close to a window so it can receive the GPS signal.
- If the device is using an external GPS antenna, make sure the antenna is connected to the chartplotter or the NMEA® network.
- If the device has more than one GPS antenna source, select a different source (Selecting the GPS Source).
