Ground Power Unit

[RodgerC 58]

This is a ridiculous question.  Just purchased this aircraft and when starting the GPU is connected to the airplane and I cannot figure out how to disconnect it prior to taxi.  Tried everything I can think of, but I never use a power unit starting any airplane.  Usually I start with engines running which is the way I set this up but the GPU was connected and can't figure out how to disconnect it.  Can someone please let me know how to do this.  Thanks.  Much appreciated.

I think I've figured out the problem.

The pop up menu?

I assume you found that just clicking on the left console button toggles the GPU.
