Well I have a problem, when I turn my car from running all the way to lock and pull the key out, my 06 OEM radio still plays music. Just started doing this today..... any ideas on how to fix this?

THANKS!

How long does it do it for, and does it continue to do it when you open the door.

Most logical answer is that the Constant and accessory inside the radio are messed up causing the constant power to get where the accessory power should be, this would cause it to stay on all the time, if it only does it for a few seconds, then it is retaining power somewhere in the car like a capacitor. I have this issue when I have my power invertor turned off (since it is hardwired in) it retains power and causes my radio to stay on for 5-10 sec after I turn the car off.
