I just got a used boat with 2 998c and an terrova ipilot link. I updated the units before i updated the ipilot. The problem is the orignal owner never updated the ipilot. The controller software is 1.130 and the remote is at 1.150 the units have 7.670 now the units wont connect to the trolling motor. HB says i need to send 1 unit in to get software reverted to an older update 6.9 or lower. I there anything i can do instead of sending it in to HB? Im going to be away for a few days so il check in when i get back. Thanks guys
