I'm really new on this forum, so glad to be here

I brought a month ago a Navigation for Volkswagen from Joying, an android head unit with Android OS v4.4.4, chipset RockChip 3188, ARM9 Cortex 1.6 GHz quad core.
After some specifications from producer I tried to use a function from menu, named GPS Mixing, which mix the radio audio signal with audio signal from GPS software. On their site they put a video with this function working, but mine doesn't. The radio signal from Radio application is hearing but when GPS software brings with audio instructions it dimming the radio audio signal, but GPS audio doesn't hear at all. I reinstall the firmware, like they said to do, but reinstalling does not make any changes. I made a video for them, I will put it here, maybe one of you could give me a resolution to solve this problem!
PS: Sorry for my english
