Did you get the famous communication error 16 when using Android Auto? Yes, the famous message “Communication error 16: There seems to be a problem….”
To solve it, you can try the suggestion that the alert shows you: disconnect and connect the mobile. However, on Xiaomi devices this solution does not work because the error seems to be related to one of the MIUI functions: the dual applications.

It is that function that duplicates Google services so you can have a secondary account for almost any app you want. And it is this dynamic with Google services that seems to cause conflicts with Android Auto on mobile.
So if you can do without the dual apps you've built, go for it. And make sure to remove any Google services that have been duplicated in the process. To do this, go to Settings >> Applications >> Dual applications >> select the wheel of “Dual Application Settings” >> Delete dual applications.
