Then after all that you'll likely end up using the controller more than the voice commands.

I have it on both X's. It's nice but not without it's issues. It seems to have most of it's problems at hiway speeds; likely because of noise from the run flats. Really not horrible though, foe the most part it works.

Where I find I use it the most is in traffic and city driving. It's well worth having in those conditions.
