M8N Tutorials: 

Multi Constellation GPS (GPS, GLONASS, Galileo, QZSS and SBAS) with HMC5883L compass. It can be mounted away from sources of interference. It features active circuitry for the ceramic patch antenna, rechargeable backup Capacitors for warm starts. 

The GPS designed for APM / Pixhawk and include cable for Pixhawk.

Change the 1.25-6P plug shell to 5P to fit APM.

NOTE: When connected to either APM 2.xx or Pixhawk, the firmware recognizes the ublox GPS 
and sends instruction to set the baudrate to 38,400, rate to 5Hz, turn off NMEA protocol, turn on UBX protocol, as well as other settings suited for use with APM and Pixhawk meaning that the "Default parameters" are irrelevant 
as they are overridden by the APM or Pixhawk firmware.
