when i push the vc button the woman's voice does not prompt me to speak and sometimes the menu that shows the usable commands does not show up. Has anyone else experienced this

i believe when u r driving, the menu doesn't come up, unless you do the flash trick to disable the security.... i do notice my car difts to right when i try to meddle with the z1 while driving.

If you have the voice muted for directions it will not prompt you when you hit the voice command button.
It will still work but it wont prompt you.
hope this makes sence
