I have the Huawei Mate 10. I just installed a JVC 830BT this weekend. I thought I messed up the wiring for most of the weekend and was troubleshooting, until I had the novel idea to try my wife's Nexus 5x. It worked fine. I saw many people say the Sony XAV-AX100 worked fine so I switched to that one this afternoon when I found it local. Nope.
BTW my problems aren't as awful as others, but when I click on Maps the first time it is a blank screen with purple lines at the top. I can click off of it and then back on, so it's not the worst thing in the world. The worst thing in the world is I cannot use my steering wheel controls to answer calls or end them, and there is no touch screen ability to do the same in Android Auto with the Mate 10. But, if I don't connect Android Auto, the steering wheel controls word just fine. I spent most of the weekend trying to figure this out, what a waste. Guess it's time to go back to Pixel.
