Hello, and nice to meet this community (this is my first post). I was looking into buying an Android head unit for my car, because I love the connectivity options and gadgets I could attach to the head unit. Also, I could use lots of Android apps and connect to the internet. My stock old Audi A4 can't even connect my phone through bluetooth properly.
As we all know, these head units have poor sound quality, and I was thinking to use a good quality external USB DAC to fix this issue. I would connect the DAC to the head unit through the USB port, and then, through the RCA cables, I would connect the DAC output back to the head unit input.
A regular android phone knows how to output digital audio signal through USB. Would this also work for my head unit. Did anybody try doing this?
