NAZA Lite and NAZA V1 GPS Mounting, Configuration, Calibration with Walkera 3 Mode Switch

I've been helping a friend with his NAZA Lite build and wanted to share how to setup the GPS. The NAZA flight controller is very stable in Attitude mode without GPS, but when you add GPS Attitude mode you get some pretty good locked in hovering.
This was setup on his F450 clone and using a Walkera WK-2801 Pro transmitter configured for multiple flight modes. To send the NAZA into GPS calibration mode you have to toggle between GPS and Manual mode 6-10 times. Then you should see the constant yellow LED where you can begin the calibration process.
