I put one of these Android units in my Subi.

Works pretty well.
Now I don't talk through the Bluetooth so I can't comment on that. It has a built in mic and comes with an external mic. Most guys say it works ok.
It boots pretty fast, screen looks good, radio reception isn't that great, but I usually hotspot my cellphone and run internet radio.
The only downside I ran into is it wont allow just any Bluetooth hardware to pair to it. Torque App supposedly works but I hardwired mine through a usb port. But I have a Bluetooth flexfuel dongle and it wont work correctly.
