The last few times I have turned the engine on, the only thing that has appeared on the audio display panel when I press the On button is the words "ENTER CODE" on the left. None of the controls will work. I cannot find any reference to this in the manual and it has never asked me for a code before. Can anyone explain what I have to do?

Hi....welcome to the Forum

 

The radio code has been lost due to a flat or disconnected battery supply.

You will need to follow the instructions in the audio handbook section and insert the four digit pin code which should be written on a card or in the service book.

This will then power up the audio system

Thank you, Trevor. I will look for it this weekend.
