With all these Garmin's being purchased/installed I'm wondering who all is using the SteadyCast Heading Sensor? I'm wanting to add one to my setup but I seam to recall, not so long ago, several folks having issues with calibration and/or general operation. I believe some suggested it was the result of a recent software update but I never heard of a specific root cause and/or resolution. Not sure if these issues were related to certain models but I have a pair of 93 SV's and LiveScope.
