I bought Garmin Edge 540 solar and from day 1 I have an issue with map tracking. While riding a blue triangle that shows my position gets stuck or moves in a random direction while blue line which shows path traveled continues tracking my movement and after a while position marker resets to a correct position until it freezes again soon. This makes me think that problem is software based (because blue line continues tracking my movement so it's not like navigation freezes completely). I updated my edge with no improvement, installed beta and problem still persists. Has anyone encountered this and knows a possible solution? Thanks
