I have been using the 830 since it was first released. Originally it uploaded rides quit quickly when I ended a ride in my driveway. Recently however, it seems to take a long time and often does not auto upload at all. I can tell the 830 to upload by clicking the upload button in history, but it still takes forever. My guess is this started with the last firmware update, but I am not sure. Has anyone else noticed this or have an explanation? Things are set to auto upload over either WIFI or the phone (Bluetooth).
