I have an 04 but might be the same. I have 3 outlets up front, some of them turn off with the ignition some don't. See if yours is the same. I just wired in a new plug behind the dash to one of the outlets that turn off. Now it is hidden and shuts off. I also wired a switch into one of them so I could flip a switch rather than hold the button on my drive&play down to shut off.
