Mission Planner / Laptop got a build in GPS

Hallo all,
I got a new Laptop wich has got an internal GPS wich appears as Com 7.
Antennentracker wise Im using the Mission Planner / Maestro / Servos wich is working fine with clicking at the Position at the Plan Map.
It would be a little bit more comfortable to use the internal Laptop GPS but unfortunately I don’t get it connected. Can someone explain me quickly how to do?
Thanks alot
