I have an older Edge 500. Works great.

I recently received an 800. When I climb steep grades, I lose the grade display. Admittedly, we're often climbing very slowly, sometimes dropping under 3mph, which seems to be the cutoff. But my old Edge 500 doesn't care how slowly I'm going.

A friend bought a new Edge 500. He too is having the problem of the grade display dropping off.

Is there a setting that we're not looking at? Or has the software changed between my older 500 and the newer 800 & 500? We are not using the GSC-10.

Thanks for any input.
