I have a Lowrance I-finder C (Color) with built in compass. When walking=20
the compass is very good after being calibrated, But put the unit in a=20
vehicle, and calibrate in the vehicle, and the compass may be off more=20
than 30 degrees. We have not had issues with magnetic needle compasses=20
in the vehicles. I guess what I'm saying, the electronic compass may not=20
be accurate in a vehicle.
