I have my Ford audio system 5000c against the JVC RW exchanged 400. Installation is relatively simple when one considers the following: - The supplied mounting frame of the radio is too large and needs to be replaced by a special mounting frame (eg Ford Focus mounting frame from 2004) - New matching visor, because the radio is smaller than the audio system of Ford - It must be subsequently ordered a DIN on ISO adapter for the antenna connector
The Radio Car adapter for FORD (quadlock / ISO) is included.
For me, all the effort was worthwhile, since a 1 DIN radio in the Focus visually hergibt not much.
