GPS very slow to aquire signal

Former Member over 7 years ago

My edge 25 never previously had any issues getting full GPS signal - almost as soon as I would switch it on, it would report that the GPS was ready.

In the last 2 weeks, the GPS has been very slow - it can take up to 3 minutes after turning on the device before the GPS is reported as ready. I have both GPS and GLONASS active, but I haven't changed the settings of my Garmin edge for many months, so I don't know why the GPS would have changed it's behaviour recently.

Is there any advice anyone can give to rectify this?

Try connecting it to your computer and Garmin Express.

That seems to have fixed it. Was there a recent software update or does plugging it into garmin express reset it somehow? Just so I know for again!

There's a file - EPO.bin - that contains the GPS ephemeris data (satellite information) that needs to be refreshed occasionally. This only happens when the device is connected to GE and a computer. It does not happen when connected to a smartphone.

There's some useful information here - https://www.dcrainmaker.com/2016/03/why-your-garmin-gps-is-better-off-taking-epo.html
