Hi i was mesing with my bose radio looking at the hookups to install a aftermarket one. and when i plugged everything back together my radio stayed on with no keys in the ignition!! i can turn it off manyally by pressing the on/off button but it should turn off when i shut my car off and it says on!! any suggestions???

 

It's a feature, that allows you to listen to the radio when the key is out for up to an hour before it turns off. Otherwise, if you key on, then off, it turns off. To turn it back on, just push the button. Nothing is wrong.
