※Added operation check on December 15th Thank you for viewing. This is a Garmin EDGE510 Japanese version cycle computer. ◇Condition Although there are some scratches and dirt on the main unit, the screen has a protective film attached, so the screen condition is generally good. All buttons and screen touch operations have been confirmed to work. Satellite (GPS, GLONASS) reception has also been confirmed. In addition, I connected to the Garmin Connect app on my smartphone via Bluetooth and checked the workout data. At that time, I also checked the trajectory of the route marked on the map within the app, and the tracker accuracy was also good. With GPS only settings, the battery consumption was about 40% in about 6 hours. The tracker accuracy was good even with GPS only, so if you want to extend the battery life, use GPS only. In areas where GPS signals are difficult to reach, such as mountainous areas or areas with high-rise buildings, it is recommended to use the GPS+GLONASS combined setting. I have only used it with the WAAS/MSAS mode, which is said to improve satellite positioning accuracy, turned on, but it is thought that turning it off may reduce battery consumption. The navigation function has been confirmed to work by creating a course on the map of the Garmin Connect smartphone app and sending the data to this unit. Also, I confirmed the USB connection with the Garmin Express software on the PC. This is a listing for the main unit only. How about this opportunity? Thank you for your consideration. #EDGE510J
