I have an S-Reg V6 Peugeot 406 (1998 model). It recently had to go into the garage for repair after an accident, and for some reason they removed the battery - I really don't think they needed to, but anyway... The problem now is that I don't know how to enter the code for the radio. When I switch it on, it says "CODE" on the display. I then have to enter 6023 as the code. First problem, there isn't a 0 button on the radio panel - just numbers 1 to 6. Second problem, when I press the 6, nothing at all happens, nothing changes on the display etc. This seems to suggest to me that it isn't actually ready to receive a code. I'd be very happy if someone on here could give a clear and reasonably detailed explanation of how to go about entering the code. I've done several searches on the net, and haven't found the information I need. I'm not in possession of a copy of the radio manual which ought to have come with the car.
