My GPS was taking forever to lock. I noticed my EPO was expired. EPO will not update with wifi, Garmin Express or syncing with GCM on my phone. It took forever, but I finally got a GPS lock with the "run" activity. Tried a hard reset and no luck. Watch still says EPO expired. Anyone have any suggestions on what to do next
I've had some instances in the past where GPS has taken a while to lock. I haven't looked to see what state the EPO file is but a reboot of the watch kicked the GPS back to life following the restart.
Thanks all for the suggestions. I finally got it working again. I had to remove the EPO.BIN file from my watch, (oddly enough it was dated 081418) and then sync with wifi and my EPO is now current (081518) and I get a GPS lock within a couple of seconds. I'm not sure if I had a corrupt file or not. The EPO is suppose to be good for a week, so I'll have to see if I have problems again later. Thanks for the link Twinaxx. I saved it for future reference. FYI for anyone using that link, the EPO.Bin can be found in the Garmin/REMOTESW folder on the 935.
EPO.BIN is always listed as 'current' on my watch, which only syncs through the GCM on the phone. However, the FR935 acts as if it has an expired EPO, it takes ~ 5 mins to obtain a fix. My Epix has a stale EPO, but is quicker to obtain a first fix. Disclaimer: comparison done only twice in the same location.
Twinaxx Mine also always showed current up until yesterday. Strange the file was dated current too. Anyway, just tried GPS fix again and counted to 3 before I got the green screen. I removed the EPO.Bin from the Garmin folder. I saved it to my computer in case I needed to put it back. Synced with wifi and all is good. Maybe trying this may work better for you too? Your link says to update through Express or GCM. I did it with wifi. Others say wifi only. Makes no sense why people can only update a certain way.
I'll try updating via USB with a downloaded EPO.BIN (~64 kB). Syncing via phone always puts a smaller file (~37 kB) on the filesystem, which is probably the same as the smaller EPOB.BIN of ~ 37 kB, valid for only a day or two, that the Epix/Fenix 3 receive when they sync via the phone. Just maybe that you get the bigger file via Wifi or GCM and that works better.. but that would be odd, a small EPO(B) should work just as well if updated often enough.
