ISSUE:  The GNS 400W/500W NavData cards are being updated to include newer memory components and can be identified by the light orange label affixed to them.  (The label was silver on previous NavData cards).  These orange-labeled NavData cards are only compatible with GNS series units operating with main software v3.30 or later.  These orange-labeled cards are only compatible with Jeppesen's Skybound G1 programmer or the updated Skybound G2 programmers.  (The updated Skybound G2 programmers will also use an orange label.  The label is black on previous G2 programmers.)

  • No action is required if using the silver label NavData data card.
  • Use of an orange data card requires GNS SW version 3.30 or later.
  • Use of an orange data card requires an orange Skybound G2 data card programmer or a G1 programmer.
