Thanks mate, I tried it a few times and just got the number I mentioned in the original post.

I'll give it another go when I go back to the car after work and see how I get on, hopefully I was just having a stupid moment and will be able to get the number to come up.

Thanks again

As it happens I have exactly the same car, OP, except mines a Zetec!

Since you appear to be having some difficulty with this I've just been out to obtain the Radio Serial Number for the radio in my car. Now, as it happens my radio is a Ford as opposed to your Sony but the interesting thing is that, when I press Buttons 1 and 6 together and then turn the radio on, I do get that 830238 number! So I do believe the radios are likely to be somewhat similar.

However, that isn't the serial number as you already know. On my radio the radio serial number is given at the very first chain of numbers displayed when you press buttons 1 and 6 and switch on. The 830238 number is in about the third chain of numbers to be displayed so I think it's quite possible that the serial number may-well be being displayed but you are missing it!

It won't be displayed on it's own, it will be part of a long chain of alpha-numeric numbers.

Mine is: FDD2006V055221 so that's V055221 This is the very first display.

I've also discovered that you can just press Buttons 1 and 6 together with the radio already switched on! Exactly the same numerical chain is produced.

Hope That Helps!

Success, the serial number is V006806 if anyone is able to help with a radio code.

Thanks again

Perfect, that works.

Really appreciate that mate, thanks for all the other help as well.
