Hi Guys, I have a Peugeot 406 S 110 bhp estate which is on its 3rd Sat Nav unit. All 3 units have failed with the same fault with the following error messages: CD ROM Missing, CD ROM Unreadable, Navigation System Initialising ( for up to 3 hours ) also some menu options "greyed out" & occasionally goes off for no reason. In all 3 cases I have cleaned the CD and the laser lense without any improvement. I suspect the problem is related to disk read errors during the initialising process. Another question, if a unit is replaced under warranty shouldn't that unit be covered for a further 12 months as the dealer wants £850 for another refurbished unit. Any help would be appreciated.
