The GPS-400 is a more focused version of the GNS-430. It lacks the VOR/LOC/Glideslope Receiver and COMM Transceiver, but is available at a lower price. It still offers the same IFR non-precision approach capability (without vertical guidance) and color Multi-Function Display (MFD). If you don't need or want another NAV or COMM, the GPS-400 is an excellent value.

The GPS-400 is best compared with the King KLN-94, since both are color IFR GPS Navigators with comparable prices. However, the GPS-400 offers some significant advantages:

• If you have flown with a member of the GNS/GNC/GPS 400 or 500 family, you likely already know how to use the GPS-400. Every GPS has its own operating logic, and it is easier (and safer) to use a navigator that is familiar.
  
  
• The GPS-400 has a larger display than the KLN-94.  (To be fair, it is also a little taller, 2.66 inches to 2 inches.)
  
  
• The King factory has run out of displays for the KLN-94, so a KLN-94 with a bad display cannot be repaired. There are no such concerns for the GPS-400.

The GPS-400 contains and integrates the following functions:

• IFR GPS
• Jeppesen database
• Moving Map / MFD

In addition to the color map, the GPS-400 can also display lightning data from a remote WX-500 Stormscope, weather data received via satellite, and traffic from a compatible source.

The GPS-400 can use any of the following Indicators, although the GI-102A is the official choice:

• Garmin GI-102A GPS/VOR/LOC Indicator
• King KI-202 GPS/VOR/LOC Indicator
• Collins IND-350A GPS/VOR/LOC Indicator
