How to connect the Garmin Edge Remote to a GPSMAP 66i?

Hi there,

m trying to use the remote of my Garmin Edge also to the GPSMAP 66i, but m not able to pair the two devices.

Ever since m having the GPSMAP m also using it as my bike computer. In many ways it is a much better device then the real bike computer (edge 1030). The only thing m missing is the remote switching of the screens via the remote. 

Any idea how to achieve this?

Thanks ... Thomas
