ANDROID How to change and edit aproaching beep in igo nextgen ?

Its the aproaching beep, not the one that is activated together with the speech of the tts voice.
Im using Gift edition 9.18.27.687519 Pongo Sking, but I guess any version should do the trick if its possible to edit it someway.
this one:


and not this one


My aproaching beep sound is always !sectionbeepB.wav, there is no lines in the sys.txt or plugin.ini that point to this sound.
and it is starting to beep before 100M of the alert, I wanted to increase this valor and control the frequency.

I tried to change the valors of aproach beep distances, but it does nothing, the beep always behave the same way, no matter how I edit the plugin.ini.

i tried to create new line under the desired [speedcam_category:XXX], but no success
approach_beep_distances="50,150,300,600"
approach_beep_spoken_type=sound
approach_beep_sound="!alert2"

my plugin.ini of the speedcam.zip UX is like this:


the line warn_distances is for activating the speech of TTS VOICE and the beep sound with it (in my case no sound)
it does not change the distance of aproaching beep.

Any clues ,nextgen is very stubborn to accept changing the beep behavior.
