Hi , I am trying to change my radio on my c3 with an after market radio by myself. While i managed to achieve my goal, the central locking started malfuntioning after this.So i checked with citroen dealer who suggested an adapter ( Part No. 947528 ) to fix this. I wish to know if just fitting the adapter will solve this issue or will it need re programming of the system as well,which I believe only Citroen are capable of doing. Thanks Tony
