Was wondering whether any one could help me out with a code for my Blaupunkt radio. I just bought second hand car Iast week and replaced the car battery and the battery in the central locking key (holden astra 2004). After this it requested a 'code'! Pulled out the radio to get the serial number and it is BP239135402356....other number details on the top was=92057951 UIE. Can anyone help? Many kind regards!
