There is a microsoft Cortana app for Android...I used to have a Nokie 929/Icon and ended up switching to Nexus 6p because $700 for a phone is insane. (Sidebar, it works on Verizon, so does the Nexus 5x). I loved the way my Nokia worked with my cars Bluetooth. I'm not buying a new car for Android auto...but like you I'm looking for a solution...everything I've read about different apps seems to be "patches". They a have a "text to Bluetooth app"...that is all it does...and it just reads it...doesn't ask if you want it read. I've had some luck using google now saying "'ok google"...pause...."read last text message"...it will read it then ask for me to reply...or "'ok google......call the wife"..... But that's about it...not as fluid... I just installed Cortana and have not tried in the car yet but I'm going to test on my commute tomorrow. Only problem is you have to have the app open to work... I've heard Samsung S-voice might work for what we are all looking for as well. Also google now doesn't interrupt am/fm or even podcasts that your listening too. I'll report back tomorrow. I've read many forums looking for a solution...some are dated. Mixed results, there hasn't been a fix all...but none I mean none mention the Cortana app for android so either people have moved on, went back, or even as one guy posted "I put my sim card in my Nokia while I'm driving, then put it in my android when I get out."
