Pixhawk 2 and Swift Navigation Piksi Help?

Setting up Pixhawk 2 to work with Swift Navigation Piksi.
GPS1 is where we are connected but can’t seem to get it to work . Outputting at 152000 baud NMEA GGA from the Piksi to the GPS1 port on the Pixhawk . Swift Piksi UART 1 .
Going through all the Mission Planner setting can’t seem to find the right combination ?

Any suggestions ??
