Because I had installed Garmin explore on my smartphone although I don't open it, but maybe it run in background. When set the Wi-Fi on, gpsmap 66sr will download EPO.bin file (locate in /garmin/GPS )that is for Garmin watch, not for 66sr.
Was there also the CPE.BIN file?
I had ask garmin Taiwan, they say gpsmap 66sr can not update CPE by wifi. You need to use garmin explore, connect or express to do it.
