How do you set the custom helicopter music?

[TTV_KinkOnAString]

I remember it was a feature.

Would help me too. I have already the speakers for the helicopter, but I dont know how.

When you are in the helicopter "Waiting room" before selecting a mission, press "E" , then select a track and press "G".

Another way to at least hear the music coming from the heli's speakers is the Audio Icon in the Tape Player controls; it toggles on/off the music/audio to project from the heli.

You need the speakers upgrade first i think.

go here:
C:\Program Files (x86)\Steam\steamapps\common\MGS_TPP\CustomSoundtrack
and drop whatever .mp3 file you got

Get the speakers update then put your spundtrack in the folder then play it via the cassete tape player
