Hello, Forerunner 955 owner here... My watch is just 1.5 months old. [010-02638-30]
I have v13.22 installed and having some serious GPS acquisition problems.
I am a long distance walker.
Generally my GPS is amazingly good. The watch finds the satellite in 20 seconds. But sometimes the watch does not even catch a signal. I start my walks from the same place everyday. I walk 1-2 hours, no gps signal. [I lose the GPS signal in every 3-4 walks, consistent.]
I know this is a SOFTWARE issue because when my watch catches GPS signal, it does not lose it, i sometimes go gas stations to pee, the gps signal indicator does not even wiggle :) I always open up the map of my walks after walking, spot on!
The BUG i discovered is weird.
When the watch does not even catch a GPS signal, after the walk when i come home, i connect the watch to PC, open Garmin Express. Click on Manage Maps, delete and re-download a random map. Disconnect the watch, let it "re-arrange" the maps. Flawless. GPS is active again with all its glory.
Now my watch does not even have maps installed, 28.3GB free space but it finds GPS signal correctly... in 20 seconds. But i know that after 3-4 walking sessions my watch will not be able to catch GPS signal.
Does anyone have the same problem as me?
