2018 Prime Plus Android Auto?

Hello friends, I know there has been threads before this about this topic but it seems most have been taken over with the newer model.

My question is that with the original prius prime (plus model) has there been any way to add android auto to the original head unit? I've looked into replacing the head unit and I would rather not change the look as a new head unit will only occupy about 50% of the original head units space, making it look weird.

I have these periods where I check in to see if anything has come out but nothing has seemed to have stuck. But every time I see a car with AA I get this urge to get it into mine as toyotas entune software is probably the worst thing to come to this earth.
