The GPS software version (3.0) allows for removal of the IFR GPS operational limitation when using a compliant antenna. As a result, Garmin has specified certain compatible antennas. These include the Garmin GA35, GA36, GA-37 and the Comant CI 2580-200, CI 2728-200, CI 2728-410. Other Comant WAAS antennas such as the CI 401-421, CI 401-460, CI 420-420, CI 420-421 are not on the list.
The Main software upgrade must be completed before the GPS software upgrade. Removal of the unit from the aircraft is not necessary.
The AFMS must be replaced only when the installation utilizes a compatible GPS antenna without IFR GPS operational limitations (see list above).
Because of the addition of 3 new XM products, custom user settings on the XM Weather page will revert to the default factory settings. Also, all user settings including user waypoints will be lost during the software updating process.
Two loader cards are required to complete the software upgrade. Please contact your local Garmin dealer for this mandatory software update.
