[C320-list] ST 4000 new question

[Donald Lawson]

Funny this has come up. My ST4000 just went 200 deg off a couple of weeks ago. No big deal but it shows me going backwards on the chartplotter. Pilot works where I point it  OK. Haven't reswung the compass yet but I am going to watch this closely. Wife has a new IPhone. Only a couple of ST4000s around me but I will ask.

(making their boats go off course) Even turning them off or placingthem as far away as possible from the compass didn’t help, they had to keep thephone’s off the boat. Has anyone else had this problem?  I have done everything test listed on 320 and sailboat owners and Raymarine board (plus grounds wires) and double check all mysettings. The only test I haven’t done is the Raymarine compass test!  I’ll do that this weekend after I check my cellphone. It funny that my autopilot problems started the same time I purchased anew phone.  Looks like I might need arudder transducer but I want to have the basic autopilot working before I hunt onedown.   Thanks, John   Holokai 2
