Just throwing this out there for more info here in case someone thinks Pioneer fixed the spotty hit and miss android auto support.
My Pixel XL (current level all software) doesn't work with the 8200NEX. I'm on firmware 1.04(the latest) on the HU.
All the update did was change the smartphone menu so you can easily disable avicsync. I've tried 3 of th cables on Pioneers site they recommend with no change.
The workaround on Pioneers site just shows you how to disable Avic Sync and says that if Avic Sync is on Android Auto won't work and vice versa..
I even pulled the HU and plugged directly into the back, even tried on the iPhone port(which works great with my iPhone and Apple car play).
The Pixel does work in a company car on android auto.
No idea if another Android Phone will work. Might try with a friends some day.
I've also reinstalled everything just in case something was corrupted.
So annoyed with this kind of thing. You get the top radio and then what you would expect to be the one phone you wouldn't have issues with (google pixel) and it's just garbage.
