The data is not usable andthe card should be returned to your Garmin dealer.Airspace ahead — less than 10 minutes — Your GPS-calculated course is projected to enter a special use airspacewithin 10 minutes. This message is automatically disabledwithin 30 NM of an arrival airport, when an approach isloaded.Airspace near and ahead — Your GPS-calculatedposition is within 2 NM of the boundary of a special useairspace and your course is projected to enter the airspace.This message is automatically disabled within 30 NM of anarrival airport, when an approach is loaded.All data referenced to True North — The unit does nothave a valid aviation database, so it cannot compute mag-netic variation.Approach downgraded — Use LNAV minima — Thismessage will occur 60 seconds prior to the FAF if flyingLNAV+V, L/VNAV, LP, or LPV approaches and WAASintegrity parameters have fallen below minimal limits. Asa result, vertical guidance has been discontinued and theLP, LPV, LNAV+V, or L/VNAV approach you were flying hasbeen downgraded.Approach is not active — The approach could not transi-tion to “active”, at 2 NM or closer to the FAF.
