Section 15 Troubleshooting
The Delphi NAV300 is designed and built to provide trouble-free performance. If
it does not appear to be functioning properly, please follow the troubleshooting
guidelines below.
No GPS fix:
• Check the satellite icon in the upper right corner
of the map view screen.
• Make sure the antenna on the unit is pointed
outward and upward with a clear view of the sky.
• Ensure that the vehicle does not have a heat-
reflecting or heated windshield. An external
antenna can be purchased from your retailer to
help ensure adequate GPS signal reception.
• The NAV300 may take several minutes to get a
GPS fix the first time you use it. After the unit
locates the satellites, it will-self calibrate each
subsequent time you use the unit, it should take
less than 40 seconds to get a fix. If you travel
overseas, the unit can take up to 20 minutes to
acquire a first fix.
GPS randomly loses its
fix:
• Make sure the antenna is pointed upward and
outward, with a clear view of the sky
• The receiver will continue to search for a signal
and will automatically recalculate the route once
reception is restored.
