Problem with the ILS on 747 Air Force One

[Pc-Shark]

I downloaded B 747 Airforce one From simviation and the ILS completly does not work. How Can I fix This?

You made sure you switched to nav mode from gps mode?

I dont have this model, but Im just giving a common problem simmers have with ILS.

The problem is more than likely in the aircraft cfg file.
look in the radio section and make sure that the first line looks like this.
nav1=1,1,0  the first number means the radio is on the second number means nav1 has the glide slope and the 3rd number means standby
1=true or yes
0=false or no
If this is not the problem than check the nav gps switch if it has one.
