Hello.
My garmin edge 1000 does not record mileage above 56.8 miles. This happened today whilst using the turbo trainer, and also 2 years ago whilst out on a ride. Although the speed, cadence, HR etc were all being shown on the unit as normal, the distance recorded did not go above 56.80 miles. All the sensors that I am using are Garmin ones.
This is a replacement unit supplied to me in 2017 after my original garmin edge which was purchased in 2016 went faulty.
Another issue with this unit is that when I use the ‘Indoor Cycling’ function, the unit shuts down after I swipe through several screens.
I am very disappointed with these products. I am in the process of training for a 500 mile charity ride in Scotland next year but I am no longer confident that my garmin edge is up to the job and I am already looking to replace with another brand.
