Hi there,

 

Got in the citigo this morning and I was greeted to 'safe' on the radio which was a bit odd. I thought I had the code and it was wrong. Anyway I left with this screen and can't change anything. Can anyone help please.

Consider changing the main battery, if it is old. There's a well-documented effect on various electronic systems with batteries that start the car but drop volts in the process, disrupting electronic power-up and CAN signals for a short period.

I didn't know that any Up/Citigo radios required a code - I thought is was CANbus these days....
