Today I made another ride with the 830 and it went well. But is it normal that you can switch between the various profiles on the Garmin during a ride? Have not noticed it before.
I went to the profile screen and back to the different tabs but I missed a lot. I was in the "Trainer" profile and I haven't set anything there yet. Then back to the home screen and there you choose the right profile.
It works fine. He also finds the sensors again.
