Desperate Help with a Rover radio code

Hello everyone.

I am sorry to be so rude as to post a request on my first day but I desperately need help.

I just bought a radio code for my Rover 75 online. It turned out to be the wrong code and I cannot find anywhere to get it.

The radio is a CD423x Rover original and the serial number is VDCD3042002863.

Is there any chance anyone could hep me please?

Thank you.

Again, sorry to be so rude.
