I recently had my 997 moved up front and mounted to my I-Pilot. This unit is linked through the interlink to my new 998SI. I'm experiencing two issues:
1. The 997 goes haywire the second the trolling motor goes into action.
2. Once I pull the trolling motor out of the water and shut the depth finder off, the 998 won't let me mark waypoints unless I turn the unit off/on.
