Can I pause MP3s on the touchscreen?

Hi All,
Not sure if I'm being dumb but ...
I was playing around with MP3s last night, moving some from my USB stick to Jukebox. Whilst playing them I just could not figure out a way of pausing the playback. I can skip tracks, change album, etc.
But there doesn't seem to be buttons for STOP and PAUSE.

I've just looked in the book, and the pause button seems to be a pic of a button on the steering wheel. Is that really the case? Surely passengers shouldn't have to ask the driver to pause a track?

We've had a standard set of buttons for music playback for over 50 years so why have Citroen decided they know better?

Any enlightenment would be appreciated!

Thanks,
Matt
