I am running an 859 DI on my boat.
This is not correct. The ONLY i-Pilot Link feature tied to LakeMaster mapping is Follow the Contour. All other features (Spot Lock, Track Record and Playback, BackTrack, Cruise Control, Autopilot and Advanced Autopilot) work with any map chip, or no map chip at all.
