problems with a320 pss

[rcpires]

I've tried some problems with a320 pss. When I tried to play music during taxi manouvres I hear "sorry captain you must have a master
avionics" (or somethink like this), and the music don't play, and also I can inform crew for take off. Anybody can help me?
Thanks, Merry christmas.

Assign a key for master avionics within FSX/ FS2004 its self, and press that key selection when you start your flight and give that a go..

Also make sure your radio panel in the a320 is switched on. If you start from cold and dark (in fact, not only then) make sure your default flight is
the cessna and the avionics switch in that default flight is switched on.
