Hi all . I have a mysterious problem wit my radio , car is 1990 4 litre sovereign , radio is standard and recently installed N.O.S , all was fine until today , i got into the car to go out and started up as usual , but then noticed no radio noise , check volume control , still nothing , everything working right , lights for dial and the FF and REW lights flashing , battery has not been disconnected or radio removed . I entered the AM code and it was not accepted , i have tried several times since to no avail. Has anyone had a similar problem , thanks in advance to all. Mark
Mark,
Never had that problem myself but a quick search of the XJ40 forum archives revealed this thread which may be of interest to you -
Hi all , Problem solved , disconnected the battery for 12 hours ( maybe a bit long ) but after that all is fine again . Mark
