New firmware seems to bring more problems and hardly any new functionality. So, why are people so eager to try the newest firmware?
Since version 16.x, it has hardly brought any functionality. I still updated to 17.28 but regretted it immediately because of a bug/feature that prevents me from silencing the audio prompt when navigating. Garmin is now at 19.xx and has never solved that bug.
If I read all the problems some people are having with v18 and v19, I wonder why bother?
