Node id How to read and set

Can someone remind me how to read and set the node id on the GNSS V2 gps.
I assume I need to have that id number and pop it into Arudcopter so it see’s the GPS correctly.
Since I don’t know what the ID number is I can set it in Arducopter.


Never mind.
More playing with the Gui and I figure it out. I had the mode id in Arudcopter but that didn’t solve the problem. Still no gps.
