Not connecting to car after recent update 0 Recommended Answers 11 Replies 8 Upvotes

Updated to the latest version of android auto which worked once but when I connected my phone via USB again a few hours later, it's as if the phone is not connected at all. The screen in my car just says "Please connect device via USB". The phone is charging and I've tried multiple cable so it's not a connection issue with the cable.
Tried uninstalling and reinstalling android auto and reset car connection settings to factory settings. Car is a 2019 VW Polo Gti.

Same issue with Subaru impreza. When I plug the phone into the usb cable it comes up with unlock to continue, which I do then it disappears and won't connect. Is very frustrating!

Hi Alice,
Could you please try the following and let us know if the issue persist. Thanks!
1. Can you check if other phones work with your car by using the same cable.
2. Can you check if your phone with same USB cable work on another Android supported car?
3. Could you try clear cache on the car ( remove the phone from the car)

I have tried a brand new genuine LG cable.
I have trued clearing the cashe and data.
I have uninstalled and reinstalled Android Auto
I have reset my phone to factory settings and completely set it up from new.
I cant try my phone in another car as i dont have one to try.
It still dosent connect to the car and i am seriously considering getting a iPhone after this experience.

I've tried all the steps in the guide and am still having the same issue. I was never able to connect AA to my Honda CR-V 2019 display. Please help!

I've tried another phone with the same cable which can connect but then frequently disconnects and Android auto crashes. Unfortunately I don't have another android enabled car to try my phone and cable with. I have already reset the factory settings for the android auto connection in my car.

Have tried everything you suggested and to connect android auto to another vehicle. It comes up with the same message "unlock to continue" then disappears and nothing happens. It's not connecting to the cars at all. New cables, different cables, nothing works. Using a Samsung s9

Not to burst anyone's bubble but what may work for you may or may not work for someone else. Generally speaking I've had success with disconnecting my phone before powering off my car. On my Subaru the usb port is not powered when I turn off the car but the HU (head unit) stays on for x # of minutes. This seems to have lessened  my issues some what.  I believe it's a poor disconnect  that  causes a subsequent connection  issue .

 To solve my problem  I must clear the cache on my AA app and let the HU power right down (approximately 1 minute after it goes quiet. 

Then I can reconnect. 

I have removed and reinstalled the app
Changed USB card
Rebooted my phone
Turned myself around 4 times 
And yet I still have issues ( with AA)
