Fenix 5 Series - Mayor malfunctions with firmware 20

Hi folks,

If anybody has any advice, please help.

The following occurred with firmware 20 update:

- Wi Fi not functional,

- GPS Version 0.00,

- Watch freezes during initial 5 minutes of the activity,

- Display data lagging,

- No connection with Windows 10, or Mac OS. The message on both systems state USB device malfunctioned.

I tried the following:

- Turned OFF then ON, several times.

- Performed Hard Reset several times.

- Kept watch outside for hours in order to receive GPS signal.

- Uninstalled Garmin Express and installed again both on Mac and Windows several times.

I've been proud owner of several Garmin devices over the past 10 years, and Garmin Fenix 5 is the first that gave me troubles. The watch is 3 years old, and it was with me during ultra trail and triatlon races. I wouldn't like to let it go.

Please advise! Slight smile

Thank you!
