Can you select 5 live extra on Sony DAB fitted to Ford Mondeo?

I have a Ford Mondeo 60 plate Titanium and am trying to access BBC radio 5 live extra on the Sony DAB radio that comes with. I'm in the UK so 5 live extra should be accessible (it is on my home DAB). Is it possible to access 5 live extra on this Sony DAB and if so how? Also is there a more complete PDF manual available for this Sony Unit on the internet (as the details in the Ford Audio manual about the Sony unit are very sparse).

Many Thanks
