This download allows you to upgrade the operating system of your GeoExplorer 6000 Series handheld with Windows Mobile 6.5 from version 6.5.8 to 6.5.9.

**The process of upgrading to the version 6.5.9 operating system will not affect your files and applications. All application data and files will be retained, however it is considered good practice to back up important data up prior to installing updates.

The update is free of charge. All GeoExplorer 6000 GeoXT and GeoXH series handhelds with version 6.5.8 of the Operating System should install this update.
