Hello

Software problem when I navigate the car I hear the announcer and the radio together
Navigation software does not lower the volume of the radio
What is the solution?

Deliberately wrote IGO8 and PRIMO file that runs the software system

sys.txt

[debug]
skip_eula=1
max_memory=104857600

For iGO to lower the music before an announcement is made, a special version of iGO is needed. None of the versions available to us can do this.
Otherwise it's down to the device itself to lower the sound through its mixer.

Try to add this in your sys.txt:

[dynamiccompressor]
compressor=1
a0="56806"
thrs=24703
ratio=9
gain=12

[sound]
media_volume=255
queue_length=100
use_os_volume=1
user_volume=255
voice_volume=255
sound_volume=255
csv_voice_enabled=1

Hope this helps
