Hi. New to this site and new to citreon. Bought a DS4 from citreon dealer 12 days ago. Car registered March 2014..Got in car tonight to find no radio, no sat nav, no phone and no central display. Noted that there seems to be comments on here re software issues. Is this common? Really gutted as love car but will have to return it if needs software patch; not paying for stuff I cannot use or have to be replaced.Thanks.
