Good morning together, I am recently owner of a 2.0 L CDI Santa Fe. Now I have replaced the existing radio with a Sony radio and matching adapter cable and it worked as well. ?BUT now the engine no longer jumps on. I can not recognize a installation error, but what is noticeable is that the symbol for the immobilizer remains on and in the start process. On starter spray the engine causes immediately. Who can please help me with tips or solutions? V G Karl
