I don't know if anyone out there has any idea how to do this, but Everytime I plug the device in via mini USB to regular USB it gives me this message (USB device not compatible) Connecting via Bluetooth works, but if I do that, then I can't hook up my phone since only one Bluetooth connection is allowed at a time. Being that Pioneer and Onkyo are together now, I would've thought they'd make them compatible or give a download patch

 

Does anyone have a workaround or suggestions? Thank you for any help

I think that device qualifies as a tablet.  I didn't think android auto worked on tablets.

Can you install the app:  https://play.google.com/store/apps/details?id=com.google.android.projection.gearhead&hl=en

 

other than that, I though the USB port is just for disk drives with files.
