Traineei found out that you can set the radio frequency using the gps, plus i found out that if you set your nav/gps to gps, and put it on vor loc the plane will follow the pink gps line all the way to your destination, to set the radio frequency, om the nav page, hit the big dial, go to APT page, hit the cursor, now use the little dial to scroll down to the runway, hit enter, the frequency is set into the radio stack, I've been flying for more than a year so ask me anything.
