sorry that i pay no attention to that post.
and sorry again that the voice gain in the factory settings page doesn't help to the navigation sound volume in fact and i mislead you before.
For the navi sound , you need to enter settings - car settings - navigation page and adjust the navi sound rate (see picture).

Ok, I will try that.. Can you still answer the following questions...

Hi Jammy, I need more information on the gain controls.
Does the radio gain only control the radio sound?
Which gain controls the Music Player?
Which gain controls the Video Player?
In addition to beeps and key tones what else does the system gain adjust?
Also can you find out what the Amplifier gain controls?

Hi,
sorry for the late reply because of the mid autumn festival holiday .
In fact, the voice option doesn't help in any sound gain . I asked our engineer and he told me that this is because that the factory software technician forgot to delete this option .
About the amplifier gain , do you mean the amp volume ? The amp volume control the voltage of the out put from speakers (Signal attenuation) . We tested one disc which contain a song professional for testing . When you set the amp volume as 0 db , and the voltage of of the out put from speakers is near 10.8V . When you set the amp volume as -15 db,and the voltage of of the out put from speakers is near 4.3V .
Regards
