im hoping you guys can help please

i have the 2008 titanium x with the touch screen radio, sat-nav, what i want to know is that when going through the radio stations it picks up i get magic on 105.4 but the signal breaks up alot is there a way to boost my reception to get a better signal?

is the radio in the titanium a standard fm or a dab? as magic is a london station as i understand it yet i am picking it up in birmingham,

thanks for any help.
