Hi i have some problems with audio and trunk. Audio not working at all,no lights nothing and a trunk is not opening as well. Ai tried everything but its opening with car key manually only . I wasn't driving with car 4 days and the battery was flat(still dont now how and why) after i take it out charged on, and put it back. Before i was doing that audio and trunk was working,after that not. Maybe somebady got same problems. all fuses is ok i checked them
