This is from a quote that was posted 5 years ago.
"Have you made any significant change in you location between rides?? (e.g. several hundred miles).
To speed up getting a satellite lock the Edge caches information about the satellites it last used, an almanac. If you make a big change in location then this cached information can actually make the first satellite lock in the new location slower as it tries to find the old satellites first before giving up on that and building in a new cache.
There is a way you view what the satellite search is doing, which might give you some idea of what is happening.
Briefly press the power button with the Edge on so that the Edge brings up the brightness page
Go to the “Set Brightness” page, and hold down on the lap key for around 5 seconds.
This will bring up a new page containing
Diagnostics
View Satellites
GPS Simulator
Select "View Satellites" it will show what satellite numbers it currently searching for and their relative signal strength. Make sure to do this in the open with a go clear view of the sky and see what happens."
