Will the 788cxi HD Combo network with the 1199ci HD SI Combo? I currently have a 1199 at the bow and 598 at the console. I was thinking about upgrading the 598 to the 788cxi HD (available as a closeout from HB) so I can share waypoints, etc. with the 1199. I know I'll need a ethernet switch but I want to make they are network compatible.
