1.7 Database Updates
The GMX 200 utilizes a database stored on an SD Memory datacard for easy updating and replacement.
The database is updated by simply inserting an updated database card into the slot in the front panel in the
GMX 200. Only Garmin approved datacards may be used in the GMX 200.
The database on the GMX 200 database card is generated from current Jeppesen-Sanderson data and
converted to a format that is used by the GMX 200. The data conversion process is performed using
software that is developed and maintained under Garmin AT configuration management according to
RTCA/DO-200A, Standards for Processing Aeronautical Data.
GMX 200 users update their database card by purchasing database subscription updates from Jeppesen-
Sanderson. The database card is programmed using a SD memory card R/W and Jeppesen-provided
software. Contact Jeppesen at 800-621-5377 or www.jeppesen.com for more information and
A separate SD memory card reader/writer (R/W) is required to update the database card using a PC.
Contact Garmin for information on databases available for the GMX 200.
