AutoInput Problem with AutoInput and Android Auto App. Can u help me?

I´ve got a Problem and I hope you can help me . And sorry for my bad english.
I want to automate the "Android Auto" App a little bit with Tasker, Autovoice and Autoinput.
I made a voice command in Autovoice wich should trigger Autoinput to click the button (red marked on Pic) in Android Auto. This doesnt work. It only searchs on Google.
The button is for going back to the main menu of Android Auto.
Ive tryed Autoinput -> Action -> X,Y Coordinates and Click, also -> Shell -> input keyevent 4 (wich should lead to the same result). Both methods dont work, only Google Now Search results.
I tryed the two methods in other apps or on the homescreen, no problem, both works.
Is there a problem with Tasker, etc. and Android Auto? Or am I making a mistake?
My phone is a Samsung Galaxy S7 with Android 7.
I hope u understand what I mean . Bad english I know.
Hope u can help me a little bit
