campaign radar help

[turkeydriver 4]

Hi guys, I've been wrestling with getting Burning Sands 1983 and I finally got it to work with only one problem that I can't fix.

The radar doesn't work in any aircraft in the campaign. It works fine for single missions and instant action, i just cant turn it on in the campaign. I can still select weapons though.

I have everything set on hard difficulty.

Any help is greatly appreciated.
