2006 Nissan Altima 2.5s.
I started my car yesterday and the radio came on as normal. When I turned off the car, it did not shut off as normal. This continued through a couple of stops.
When I got home and turned off the car, the radio was still playing. I disconnected the battery, the radio stopped. I reconnected the battery and now the radio will not turn on but everything else in the car is working fine.
