GPS fix time increased, change in CPE.BIN format?

Hi everyone,

for quite a while I am noticing on the FR 945 a longer than usual time until GPS fix, also some sort of bug (more below).

Location is North of Switzerland, tests performed outside with clear unobstructed view towards sky.

SW is latest 13.70, GPS 6.60

GPS is set to GPS+GALILEO

Sometimes a fix can be established after a few seconds. This is usually the case if a GPS activity has been run no earlier than one hour ago.

The first GPS activity of the day will sometimes take one minute or more for the GPS fix to be established, there also seems to be a bug, where the indicator will flip between red and green, but with no beep/vibration indicating the fix.

Compared with the older FR 935 which still establishes GPS fix within 10s the FR 945 is noticably slower. The more recent Fenix 7 which also uses CPE.BIN also establishes a fix within 10s. So I wonder if Garmin changed the CPE.BIN format and did not upgrade the FR 945 GPS software accordingly as it seems the ephemeris data is not properly evaluated by the watch?

Does anyone have some background info on that (yes I know it is an old discontinued watch, but still...)?
