Here's an old project I found for the v800 but that has worked great for my m400. https://github.com/profanum429/v800_downloader https://github.com/profanum429/v800_downloader It will download recordings via usb and convert them to tcx automatically :) It's saved the day numerous times for me when polar's sync app was acting buggy - saying it uploaded a run but not completely uploading it. They don't give you binary's but I was able to compile it fine on my mac.
