NOTES
Miscellaneous parts and hardware such as RF Shields, Mylar Board Insulators,
knobs, and certain screws may be available but are not listed in the tables.

Contact Garmin for the correct COMM Board service part number if it is being
replaced.
The main board contains an EEPROM memory storage device which must be
programmed with Unit Configuration, TAWS/Terrain Configuration, and Unit
