Chubaka885 thanks that link worked. I installed them and Toppal came back but he could not hear me!. what i am trying to get to work is the voice button on my steering wheel to launch any assistant ideally google assistant or toppal. but when i press the button inside google auto nothing happens. how can i map it to launch google assistant. i am using simple soft canbus , the rest of the buttons work. volume , track , source. only the voice one does nothing!
