Com/Nav Gauges

Hi there,

I am customizing my vc and trying to make space for a gns430. I can do this by eliminating my nav 2 radio which is the same size as a gns430, but the gns430 acts as nav/com radio one.

What I'm asking is: Is there a way to tell com/nav 1 gauge that it is now com/nav2?

Cheers,

Loren
