The following lists of changes are based on information provided by GARMIN. Changes or improvements which we consider important or especially useful are shown highlighted.

To view the current GPS Chipset Type G software version, complete the same steps as for viewing the firmware version. GPS devices equipped with the Type G Chipset will show both version numbers on the same screen.

Each upgrade replaces the complete Chipset software in the GPS, which means you need to install only the version you wish to apply. There is no need to install any previous versions.
