Just had to fit new battery in my car, unfortunately I couldn't find radio code in my service/manual book. Tried to use one code already and got an error msg on screen. I'm unable to find original dealer where my car was bought in - no dealer stamp in service book - to get service for free. I found those details on radio chasis:
Radio Tuner List model no. RENRDW100-10 R571 SECURITY RNRD0140211653 Prod no. FD0404300211653
and where the barcodes are: 8200247962TR571 8200 247 962
