Edytab 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
