Hello,
I was told by this website (https://www.thisisant.com/directory/varia-rvr315) is compatible with the old reliable Garmin Edge 25.
I have the 2022 Cannondale with smart sense with the Garmin ERVR 315. The Edge 25 can't sense the the radar.
I have updated the firmware on the Edge 25 as well.
Any solutions please?
