It might be in the Navigation voice command menu. You shoud be able to get to it by pressing the voice button then selecting "more commands" then select "navigation commands"
I think there's 10 or 11 moe commands there.
I just have not messed with it yet, probably should check it out this evening
I was about to start a new thread, but then I found this.
Is it truly not possible to stop guidance using a voice command? That must be one of the stupidest oversights ever! And I thought Land Rover already owned that crown with the no-preset selection from the steering wheel buttons...
As I always say, I love this car, and I like using voice commands, because the voice recognition system is generally very good (the Grand Cherokee we recently rented was awful), but these kinds of oversights (that you know will never get fixed) are truly annoying.
