Last Thursday my car battery died completely so had to get a new battery fitted, since it was fitted I have not been able to use my radio, my hubby found a video on youtube that tells you to put in code 652 but that only makes the radio work for 2 minutes at a time, and I have a nagging 6 year old that loves his music!!! Is there anyone who can help me please as every site I have seen want to charge around £15
