Sorry, yes (or rather no), I was confusing that setting with the one that lets you set how aggressively the volume is reduced for the park-assist. However, what I said about the volume reducing for SatNav announcements is still correct - it does do this automatically, but only if the audio volume is above a certain level (which it won't be unless you're listening to audio that hasn't been 'normalised' to an inch of its life). Easy to test/experience, just turn your radio up loud and then press the right-hand knob to get the satnav to speak - you'll hear the audio volume reduced while the announcement is made.
