[TG11] Smart Pilot X-5 Wheel Pilot

Hello Metta Marine,

No, I'm sorry to say you can't do that: the EV1 is an autopilot course computer in its own right and your system won't react well/predictably to having two course computers installed.
We don't recommend trying to use external heading on an SPX pilot because although the EV gives very accurate heading data, using any external heading source disables some aspects of the SPX's steering algorithm which rely on the integration of the analogue fluxgate and rate-gyro data within the SPX. In addition, NMEA2000 heading is only 10Hz which actually isn't all that fast if you're trying to operate a pilot from it.

I'd keep using the fluxgate until it's time to replace the SPX.

Regards,
Tom
