Formats - Welcome. Here you will find documentation on the file formats used in Garmin devices as well as sites that integrate Garmin devices in data transfer, such as MotionBased.
General introductions, FAQs, and schema documentation are provided for the various formats. Keep in mind that some of these formats are Garmin specific (i.e. AXM, TCX), while other formats were not created by Garmin yet can be used by Garmin devices (i.e. GPX, KML).
