you need to remove the radio. 
they are too small holes each side of the radio 
use an old metal coat hanger 4 darts or very small screwdriver or long nails. 
put into holes about 4-5cms and push outwards sideways 
and carefully pull radio forward. 
you must do the holes on each side at the same time 
Then post the numbers/letters from below the main barcode 
something like 7700xxxxxxtt123 or 8200xxxxtt123 or 
the security code like Q123 or T0U123 
can be found in a small box then i can help you 
off of the radio
then mail me at codehelp(at)hotmail.co.uk
