Alert Text 

Possible Cause 

Solution 

check GPS antenna (main 
software version 3.20 and 
later). 

 Internal system-to-system 

communication between the 
main processor and the GPS 
receiver has failed.  
Operational status of the GPS 
receiver is unknown. 

  Contact Garmin technical 

support. 

GPS needs service 

  The 400W Series unit has 

detected a failure in its GPS 
receiver. 

  Contact Garmin technical 

support. 

Large magnetic variance 

  A valid value of magnetic 

variation is not available for 
this location. 

  Verify all course angles 

  Contact Garmin technical 

support. 

  Improper antenna installation 

or coax routing 

  Check GPS antenna 

installation, connections, and 
cable routing.  The GPS 
antenna must be mounted on 
the top of the aircraft. 

  Antenna shaded from satellites 

  Make sure the aircraft is clear 

of hangars, buildings, trees, 
etc. 

Loss of integrity — cross-
check NAV 

  RF interference at 1575.42 

MHz from VHF COM.   

  Move GPS antenna further 

from the COM antenna. Add a 
1575.42 MHz notch filter in 
COM coax.  Fix or replace the 
COM.  Disconnect the ELT 
antenna coax to check for 
possible re-radiation. 

Low Battery - Unit Needs 
Service 

  Time data may have been lost 

due to a memory battery 
failure. 

  Replace the battery (refer to 

Section 8.4). 

MAIN processor requires 
service 

  The 400W Series unit has 

detected a failure in the main 
system processor.   

  Contact Garmin technical 

support.

received from RS-232 
(Serializer: Icarus, Rosetta or 
Shadin) or grey code inputs.  

  Refer to Table 6-1  

“RS-232 device is not 
communicating with the GPS 
400W/GNS430W”. 

No basemap data available 

  The 400W Series unit has 

detected a failure in the built-in 
basemap (land data) memory.  
Land data does not appear on 
the Map Page.  Other unit 
functions continue to work 
normally. 

  Contact Garmin technical 

support to reload the basemap 
data.
