The 2004 model no longer has this fitted. Whether this means that the old system is no longer available as a retro-fit, I don't know. I've been trawling through the Renault site and some brochure PDFs but can't see it as a retro-fit option?
My mates 03 Laguna had this fail on him. He had so many faults he returned the car after 3 months and he much preferred the beeps in the replacement
