Issues with Grade and Elevation Calculation on My Garmin Edge 1050

Hello,

Sorry for my english.

I am writing to report an issue with my Garmin Edge 1050, which I purchased a month ago. Since yesterday, the device has not been functioning correctly in terms of calculating gradients and elevation.

During my last ride, the road gradients displayed were completely inaccurate. For instance, while riding on a slope of 18%, my GPS was showing -11%. I have tried everything to resolve this issue, but nothing seems to work: the gradient calculation is not functioning, and as a result, elevation is also not being calculated.

Strangely, the ClimbPro feature does appear and shows the gradient that should be present, but in real-time, the displayed values are almost always negative.

This is particularly frustrating for a brand-new device. I have tried resetting the GPS, but the problem persists. To give you an idea, during my ride yesterday, my friends recorded a total elevation gain of 2138 meters, while my device barely showed 500 meters.

Could someone assist me in resolving this issue?

Thank you in advance for your help.

Best regards,
