GPS ports configuration

Hi

Hope you can help, currently setting up my new pix 6C , ive changed from a minipix.
i currently have a 6 pin M9N Gps. now the 6C has a 10 pin GPS 1. and a 6pin GPS 2.
i have been told by the supplier that i can use my 6 pin Gps in GPS 2 port…
In mission planner though i have GPS no GPS, GPS2 3D FIX.
SAT COUNT - 0.00 SAT COUNT 2 -24.00…
is there a way to make the GPS2 port the primary port so that mission planner sees this port as GPS 1 for instance…

think ive found it

That looks about right to me.
