This trick does not seem to work for the 6-speed-MT. I'll keep trying other things...Took me a while to figure this out. The way to do it is to put the car in neutral then push the start button once. This will shut off the engine, but leave music/nav/etc running. You can put it in park afterwards, just don't forget to do so, LOL.
Please tell us if you finally find out how to do it in the MT model!!. I will also try and ask my dealer.
