Garmin accurately processes and cross-validates thedata, but cannot guarantee the accuracy and completeness of the data.The terrain database is updated periodically and has no expiration date.UPDATING G3X DATABASESNOTE: The databases are stored internally on each GDU. When updating asystem with multiple GDUs, each GDU will need to be updated individuallyusing the same SD card.The G3X database updates can be obtained by visiting the ‘flyGarmin’ website(www.fly.garmin.com).
