Hello,
Just bought a magene S3+ cadence sensor certified ant+ (CAD, SPD) the sensor works only on cadence mode (ant CAD) or speed mode (ANT SPD). Etrex 32x is compatible only with "CAD&SPD" ANT profile.
Please see page: https://www.thisisant.com/directory/etrex30
It is possible to demand a firmware update to add the "CAD" profile to the etrex? in any case the etrex does not offer the possibility to show the speed data of a "CAD&SPD" of the sensor.
I'm really happy with my device, but the documentation is not really clear about ANT compatibility.
Thanks
