Hi, I purchase the cable for gps (GPS2)…

Until now I have always used M8N which had two information (GPS + Compas I2C).
How do you advise me to add the compass to the RTK Ardusimple Rover that does not have an integrated compass?
 
I can merge the information from another GPS (M8N for Example) …. or i can use just the I2C port of pixhawk to detect compass information of another GPS.
 
Best Regards.

I am using the internal, built-in, magnetometer included in the pixhawk.  Seems to be working well.

Magnetometers are not designed to be electronic compasses, although we can use them as such.  Confidence levels in that use should be monitored with great care.
