Having trouble getting the unit to work correctly, motor is brand new 9.9 honda, boat is 26' starcraft islander (aluminum.) Installed as per instructions, have full manual function of steering and throttle control works great. However when we try to calibrate it as per the manual, with the circles, until the compass calibrates and shuts the unit down on its own, the unit will not hold a course at all.
-The wire from the head unit to the compass ball is under the port gunnel, away from any other power/transducer cords.
- Compass ball is at least 2' away from any ferrous metals, speakers, radios. it's up in the cuddy, mounted to wooden shelves near the centerline of the boat.
- several times now we have gone through the calibration process and the unit shuts off as per the manual, which is supposed to indicate a successful compass calibration, however even after this, and adjusting the rudder gain/sensitivity. the unit always seems to end up going in complete circle.
Has anyone installed one of these units? Garmin hasn't been super helpful, and neither has hodges marine where the unit was purchased from.
Thanks in advance.
