Anyone have one of these yet. I have heard they are not compatible with Android Auto on the 4100NEX.

Looking for confirmations.

I would join this community and ask for answers there -- something is different with the Pixel (XL) that will more than likely need a workaround:

I have a Pixel XL but I am running Android Auto on a 8200nex.  Everything works great with an exception of the phone volume being really low.  If anyone has feed back on this please let me know.  I did have to use the original data cable that came with the phone to make it work.
