Manual as standard, but the best bet is to remove the wheel arch liner and have look, or take the radio out and look for an auxillary output from the radio connected to something.
They're pretty easy to fit cost £30+, to get it to go up and down even without an aux output you can get a switch to do it. You can even get black as well as silver masts ECP and GSF do them as well as Halfords and other motorfactors.
