Garmin checksum files store checksum data used to detect errors in Garmin device files. They are associated with map and voice data used by Garmin GPS devices and navigation applications for mobile platforms.
The checksum helps compatible Garmin software or a device verify that related data has been transferred or stored correctly. The file is an internal part of the Garmin data set and is not intended to be read as a standalone document.
Garmin Connect is Garmin's multiplatform service for working with compatible Garmin devices. These checksum files are handled as part of device and data management rather than opened directly by the user.
A sum file is not normally opened manually. Compatible Garmin software or a Garmin GPS device reads the checksum data automatically when it manages the related map, voice, or device files.
On supported platforms, use Garmin Connect for device management instead of trying to open the file in a text editor or general-purpose application.
Garmin checksum data is not intended for conversion to another file format. The checksum is meaningful only in relation to the Garmin data it verifies.
To move or update the associated data, use Garmin Connect or the compatible Garmin device software. Do not edit or convert the sum file manually.
