Does anyone know how to add and setup the GPS compass on the Matrice 210 when a camera is mounted on the top?  I am getting mixed info.  Hopefully the DJi Admins can answer this.

Hello, Sir, here is the tutorial video about how to mount the upward gimbal and external GPS, please check it out and hope it helps:

Thank you, Mindy.

Also do I have to do anything in the DJI Go 4 app regarding the GPS compass?

Hi,
there are 3 rows of pins, plug it into the middle one (the one with the most "to the right" pins) and put it in the last pins (looking from the left it would be pin 4,5,6,7 ending at the right most pin).
Make sure you route the cable under the external compass (or under the arm, i dont remember) so it will not get into the props.
Then just calibrate the compass and thats it.

Done, Thanks!

drklion22, do you think using the External GPS improves reception and accuracy when not using a top gimbal setup?
