Hi there
Recently got new android HU for my bemmer. It all looks ok and works properly apart from sound, I'm unable to get a sound from it. I've tried with aux port connected in armrest, without it, with aux port selected before taking down original HU and also without it, changing all possible setting on HU but only I'm getting is sound from google maps navi on my left speaker in my car. Also, if music has started while in navi, you can hear music for a few seconds while navi voice is active saying where to make next turn etc, for a 3-4 seconds, also just on my left speaker. HU is chinese from alliexpress (HFCYJIA Android 9.0 Car Screen For BMW F10 F11 Audio Carplay GPS Navi Stereo 8 Core 4+64G
