Hi, it would be great if the volume control buttons ( Touchscreen and swc) had two functions: 1st normal overall volume control and 2nd volume control of the navigation voice while it's speaking. This is the standard behavior of the swc in many cars for example Volkswagen.
On DuduOs the navigation voice is on a separate audio channel which is already controllable in the settings. So it should be a quick win to implementate the volume button control while the navigation audio channel is active.
