Heya!
1) You'll have to turn on the radio in the pedestal.
2) What exactly do you mean by this? I can change the code no problem.
3) They maybe are located under the APR VIA section
4) Thanks, will take a look at this one
5) You'll need to enter the Identifier and not the frequency
6) The frequency probably didnt autotune
9) It is there, but you won't be able to hear it from the cockpit, as in real life.
