F50 electrical problem

i need some help on my electrical problem that just happened....well what happens is when i turn my car off all my lights, nav and radio stay on....the only electrical thing ive done is i added a sub/amp the other day and this never happened......anyone have this happen

do they eventually turn off or what? never heard of this issue.

i can turn the lights off, but i have to go to my display menu and turn off the screen other than that i dont know howlong they would stay on

i would say remove what you installed

You probably F'ed up something. Take it out then turn on the car and see if the problem is still there
