I've just purchased a 2004 Micra, 1.2 SE. The radio was playing up, so I put a newish Sony in. Fitted straight in, no problems, but now I can't get the digital display above it to work, seems to have no power. Can anyone tell me if it needs to be connected to the OEM radio to work, or if there's simply a power lead I can connect to or something ? Thank you
