I have a 997c SI at the console and a 858c at the bow with the Interlink. It used to work fine sharing waypoints, but now I'm having a problem. I select fully participate in network and I get a message saying synchronization in progress. It takes a long time and then the bow unit will say participation canceled without me touching anything and none of the waypoints from the console unit to the bow unit will get updated. The accessories page says the interlink is connected. I have it connected to the interlink as suggested. Thanks.
