I mean this sincerely, but see you using it correctly?
Don't get me wrong, the use method is stupid... But it does work for me about 99 percent of the time.
The button on the steering wheel is for local commands... Like "Call John" or "Go home"
The button on the mirror uses online search and is COMPLETELY DIFFERENT than the button on the steering wheel.
Here is a video of it taking everything I throw at it. (First search was using the steering wheel button to show that always fails)
All subsequent searches were with the mirror button.
