What exactly do you mean by "the whole dance"? I've found Android Auto to be pretty simple to use. There's just one short USB cord I plug in right next to my shifter and I'm done. Everything comes up automatically. This is on a VW Golf, so maybe it's simpler than it is for you in the Focus?
Most of the problems I've had have been software bugs. Like this morning when I attempted to send a Hangouts message. The assistant voice made it sound like it worked, but nothing every actually sent.
Anyway, I'm not sure a screenless device is really what you want. Most of the appeal of AA is that it uses your regular phone, so it can use your data, read and send message, make calls, etc.
I left more specific feedback in another part of this thread.
With regard to the screenless device, I do like having my phone be the centralized device of the entire thing, I just would like to make it a more permanent part of the car so I can just hop in and drive.
I am debating trying a spare SIM and an old device and just leaving it in there plugged all the time, but that just introduces an entirely different set of problems.
