Bob,

A few things to check:

• My 55 has a heading sensor in the forward cabin bilge storage.  That is the first thing I would check.  At delivery, Kevin made a point of warning us to keep any ferrous metal at least three feet away from the sensor.
• I am not on my boat, but in looking at the manual, there is a section under initial setup that should indicate if it is receiving heading sensor information.
• Easiest way - Email Stephane at Pochon (stephane@...) with the question.  Include hull number, Furuno model number.
