My 645, which is several years old has two errors that are becoming more frequent:
1. I get an error message when I disconnect from the charger that the charging cable is not appropriate for the device. Yet it is the one that came with it, charging is successful, and it will sync with Garmin Connect and other programs. I've cleaned the contacts. What gives?
2. Becoming more frequent is that when I finish charging and remove the watch, I find that it is frozen and requires a reset to operate properly. Of course, this require waiting around for it to find satellites. Why is this happening?
Thanks,
John
