I will check with the factory, whether Campagnolo implemented full interaction with Edge 530

I spoke to my opposite number in the Service Dept at Campagnolo early this morning.

In translation (so maybe some loss-in-translation from what he said) - he tells me it works on the 530, set up is the same as with other Garmin devices, so you need to enable the sensors just the same - but since the last revision of the firmware, there is a difference ... after about 35sec, the device sensor connection goes into "sleep" mode.

It means that, if you press the MODE button to scroll or set a lap, after 35sec,  the Garmin behaves as if the sensor has just been "woken up" - the may be a short delay and a tone, telling that the sensor is connected.

Once the sensor is "woken up", the connection works as it does with G1000, 820 and 520.

now is working .problem was eps remerber last garmin 830 . during pairing i press mode buttom times , and left button 5 times . and then i show remote on garmin displey.

Ah, great!
Glad that the resetting routine worked for you.
I have seen cases where the Garmin needs to be rebooted, as well as the EPS system needing to be disassociated from another unit. Semms that is what worked for you.
