I had a similar issue. Check in the infotainment screen if android auto is disabled. That was my issue. It somehow got disabled

 

Also, may be worthwhile to uninstall android auto app and reinstall and restart the phone and try again.

Check to see if android auto app has any updates available, if auto update is not on.

 

Yep, that's the first thing I tried. No luck.

I'll check the infotainment screen and see if AA is disabled. Not sure how that would have happened, but I work in software development, so it wouldn't surprise me.

 

I will try tonight to see if it works for me. Wife usually drives the van and I haven't driven it since Saturday. It was fine on Saturday. I did get an update this morning for both Android Auto and Google Map app. So maybe that will fix the issue? What phone do you use? I use a Pixel 3 and noticed it is buggy sometimes and usually it's fixed if I unplug and plug the phone again. Just convinced my wife to switch to a Pixel 3 also from an iPhone 7. No more switching cables back and forth for us.

 

Try another USB cable!
We killed 1 out of 4 USB-C cables on during the last family road trip / vacation. If yours is on its way out, you may get the above scenario.

Thanks for these hints! I was having trouble in my Insight, but not my Odyssey and turns out, my phone was disabled somehow shortly after setting it up. Change cords, and did all sorts of things, but didn't think to see that there was a disable phone option in the settings of the Honda.

 

I had a similar issue where my infotainment system froze up and then CarPlay stopped working.
I had to turn off the car for an hour for the system to reset.

 

I'm having the same problem on my 2018 Honda Odyssey EX-L. I have a Samsung 9+ and it worked fine until a couple weeks ago. But recently Android Auto went grey and keeps telling me it's disabled. I've enabled but it still won't work. I also deleted and reinstalled the app but nothing has changed and I'm getting the same error message. Any suggestions are appreciated. Thanks

 

I had a similar issue and was able to fix it by disconnecting and reconnecting a number of times.

 

Press and hold the volume button to do a reset on the van's head unit.

 

Thanks for the advice. For me, the only thing that worked was a factory reset of the infotainment. That forgot my devices and once completed worked like a charm. Happy Driving!
