I Bought a N Reg 405 Its got a Clarion PU - 9679A radio fitted. Display stuck on "Security" but can play radio with long beep tones. Rang Peugeot dealer and got the code, had to remove radio from car to get radio Serial Number When I put the radio back into dashboard . "security" was displayed again , but when I pressed a button the display has gone off completely.
Is this because I had radio disconnected from batt for few hours? I have checked the wiring connections and they are fine.
Any help would be most welcome
