Firmware 18.26

I don’t believe there is an 18.26 version. There was a time zone update but that’s wouldn’t change the software version.

Checking out a couple other forums it does seem to be a bunch of talk about a mysterious 18.26 at least with the 255/955 but not official Garmin info.

Soy de argentina y tambien se actualizo mi 965 a la version 18.26

I had also the 18.26 version, but I don't know what is included. 

I've got 18.26 update as well. No changelog available here on forum. In beta program there is 19.xx version already so looks like some mid version.

The weird thing is that I am not enrolled to beta programm

This isn’t a beta…it’s likely an out of cycle release to fix some “significant” issue. This was the same thing with 18.23 that was released shortly after 18.20 which was the official quarterly release.

Same here,18.26 no issues at rhe moment

Long install time plus two reboots.

It seems the same happened for FR955 and FR265 (and possibly for FR255)
