Sharks.... I got a unit few days ago and tried Android Auto connection yesterday. It didn't detect and I tried a few more cables. I had no problem with at least 4 other Android phones (Pixel, Sony) and iPhones. If this doesn't work, I will have to change to another manufacturer.
Just got my X8 a few days ago. Wireless Android Auto was working fine for 2 days until yesterday. Wired is working though.
