after update to 16.17 firmware i have a problem with GPS

I upgraded my garmin 255 music to 16.17 firmware. I did factory reset and I have 2 problems

  1. I ride my bike, ang GPS stucks after a while. I stop my activity and I try to create one, but is is not possible fo fix gps
  2. sometimes GPS fixing is unstable. I start new activity, GPS after 1-3 minutes GPS s locked (green circle in display) but after a few secons it disappers (red circle on display)

till this update, garmin worked very well. any advice?

  • Same. After upgrade to 16.17 GPS is consistently out of whack. Garmin, can you please issue a fix ASAP? Fall marathon are coming up!

  • Same here - The problems started with the update to 16.17 (GPS: 5.00) on my ForeRunner 255 music...
    Please fix that issue asap - the watch is worthless more or less without working GPS (all data and calculation based on distance is corrupt) ...
