My 307 cc contact always remains open

Friends, for a few days, this problem is very interesting in my vehicle. For example, when the vehicle is running, I will turn off the ignition, I turn the ignition off, I lower it to the next level and get out, but the problem is that the light is on, the headlights remain on the screen, the car does not lock up, if I turn it on, turn off, turn off the door, sometimes it turns out to be off the door. I try as much as I will last contact laska. What could be the problem? It is a very interesting and annoying situation. This problem actually came to me as if it happened after the double din tape was connected, after all, the room was contacted but I do not know if it could be related to it, it hurts me very much, I am surprised what this will do. 29:58

it may be due to the incorrect connection of the connecting person, remove the battery head, wait a minute and reconnect it. You will reset the brain of the vehicle.

double din wrong connected problem solved .. thank you friend who helped
