[CA] [CA11] ITC-5 for i70s

RE: [CA11] ITC-5 for i70s
sailshade,

Q1. I have found a third party NMEA2000 sensor ffor a mere 150$ which also claims 9 axis compensation. I must assume it comes with lower performance and does need calibration but I am looking for a solution in that price range, so would it still work adequately with the i70s?
A1. The i70/i70S MFIDs will indeed support repeating heading data from a NMEA 2000 heading data source. However, any calibration/alignment required for the third party sensor would have to be performed in the manner specified by the sensor manufacturer.

Q2. Alternatively would a GPS from lets say an AXIOM7 be able to feed heading data to the i70s (it would cost about the same as an EV-1). I understand there is (or might be ) a significant difference between boat (hull) heading and course heading as measured by a gps (due to drift)
A2. Per the previously referenced FAQ, GPS sensors (with the possible exception of a GPS compass) are incapable of sensing magnetic heading unless they have been additionally designed with additional magnetic north seeking circuitry (ex. some Airmar weather stations are feature heading output). Raymarine MFDs are likewise not designed to sense magnetic heading. Like external GPS sensors, the internal GPS sensors of Raymarine MFDs are designed to sense position, COG, and SOG.
