My chartplotter will not acquire GPS signals

If the device is not acquiring satellite signals, there could
be a few causes. If the chartplotter 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.
• Make sure the GPS antenna has a clear view of the sky
to 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.
• Make sure the GPS antenna is connected to the
NMEA network.
®
• If the chartplotter has more than one GPS antenna
source, select a different source.
• Ensure the device is using the latest software, and
update the device software if necessary.
