To make my 798ci si combo talk to my MK Terr. Ipilot Ilink so I could use it to follow contours on my home lakes in Ill. Ky. ( think it is the east region ) I don't have a LakeMaster or Navionics card in ether one of the units. I know I will need one so if someone has one for my area.. please chime in. Also will I have to download something on the remote for the trolling motor to read such thing. If so were do I go to do that and what will I need. Do I go to the Hbird site for these upgrades? Unites are NOT HD.. Thanks Fish
