Android Auto not working via USB with S9.

[DaddyP]

Since early September, Android Auto will no longer work via USB in my car with my Samsing S9. Prior to then, it was working perfectly.

I've reset the phone, the car's head unit, cleared out the cache and data storage on Android Auto, Google Play Services and Google Maps.

I've changed the USB cable too, but nothing has made any difference. The car sees that something is trying to connect but it drops immediately, then repeats the cycle ad infinitum.

Weird thing is, it all works fine with my A5....

Any suggestions?

I can confirm that different devices behave differently with different usb cables in different cars. Even the  tolerances in identical cables can make a difference to connectivity.

Buy a reputable cable with the fastest transfer rate you can afford. Expect to try out different cables before you give up!
