HI all got a tomtom permanent fitting kit & a parrot loom with proper iso to ford quadlock cable which I intend to fit into my 2008 galaxy ghia which is fitted with the sony gen2 head unit,I have the set of four radio removal keys but can't find any slots to fit them in so does it mean I somehow have to remove a "faceplate" to get at these? Don't wannt to start ripping things apart without being nescessary
