Hello all. Just joined this group and wanted to get some advice if possible. I have a 2012 508 SW with a buggered multimedia head unit. This is the thing that gives you your audio, GPS, reverse camera and other bits of info. It plays no actual role in the function of the vehicle, but things just seem a bit quiet. I am told, reliably or otherwise, that the ROM chip is U/S and a replacement unit is the only answer. They are no longer available and seem quite rare second hand from wreckers or any other source. Peugeot also has to re-code the firmware so that a replacement unit talks to your VIN, but first you have to find one that matches.. Any thoughts would be most welcome. The part number on mine is 98 026557 80.
