Gimbal tracking at power up

I have my simpleBGC connected and talking to the cube. On the ground “point camera here” is working, but at every power up the gimbal appears to want to face south. I dont have any POI or missions saved. Where is it trying to point? Can I have a default POI at power up? Can I change the mode at power up, ie yaw tracking (think its called RC targeting)?
I know after power up I can change it with MP but I want to change the initial targeting.

I’m guessing it’s pointing at zero lat/long and as I’m in uk that would be south.
