Sorry you had a different experience, but voice anything didn’t work with MCU1. It took forever and usually timed out.
One thing I noticed is that the "technique" to input voice commands changed over time. In my MCU1 cars with firmware 9+ I had to press the "talk" button, speak, and press the button again to advise that I was done. Used to work well.
With the "spoken sentences" firmware 10 update doing this now always leads to the voice command timing out with no action. Instead it now behaves like the OG system (think 2013) where the button was only pushed once, followed by the spoken command. Works fairly well, even with MCU1.
