Individual obstructions may be shown if available in the database. However, all obstructions may not be available in the database and data may be inaccurate. Never use this information for navigation or to maneuver to avoid obstacles. Terrain Proximity information is based on terrain elevation information in a database that may contain inaccuracies. Terrain Proximity information should be used as an aid to situational awareness. Never use it for navigation or to maneuver to avoid terrain. Terrain Proximity uses terrain and obstacle information supplied by government sources. The displayed information should never be understood as being allinclusive. NOTE: The data contained in the terrain and obstacle databases comes from government agencies. Garmin accurately processes and crossvalidates the data but cannot guarantee the accuracy and completeness of the data. System Status The Terrain Proximity system continually monitors several system-critical items, such as Terrain Proximity database validity, hardware status, and GPS status. The Terrain Proximity page will post the message "NO DATA" when the terrain database is not available. A blue cross-hatching pattern is shown when out of the area of coverage, but no system message is posted. 64 190-00356-30 Rev H
