1) DISC+ SOURCE LIST OPEN/CLOSE
2) OFF SOURCE ATT OPEN/CLOSE
3) MODE PTY/DSPL SOUND OPEN/CLOSE
4) SOUND MODE ATT OPEN/CLOSE
5) MENU ENTER MODE OPEN/CLOSE
6) SEEK- SEEK+ MODE OPEN/CLOSE

If it's a sony m800 it has a customer entered code so you won't be able to retrieve the code from the serial number so I'm afraid you will have to take it to a specialist decoding firm, you should be able to look up your local car radio decoding company in the phone book

Put new battery and battery light turned on


What is year--make--model? I'd have to check wiring circuits to and from charging system, also, to and from battery.

Can you check for applicable trouble codes? Some makes and models if battery voltage is lost, it can cause problems with some vehicle systems.

Lost code for sony cdx-m800


You can enter a 4-digit security code as an option after purchase of the unit. If you do so, make sure it is noted down somewhere. If you did select a code (or the previous owner has done so) this must be used when the unit is removed from the vehicle, or the constant power source is disconnected from the unit. When constant power is restored to the unit, the security code must be entered before the unit becomes operational. If the code is lost or forgotten I am afraid the unit has to be re-coded by a Sony dealer.
Hope this helps, Good luck with it.

Hi,

I have got a Ford Mondeo and the same thing happened to me. I took the car to an official Ford dealership and they reprogrammed it for me and gave me a new code. And best of all they didnt charge me a penny.

Cheers,
