I think it would. (don't hold me to it) I may be thinking of the Audiophile unit though. Since that is usually the unit that comes with the upgrade. I'm sure there is a way to hardwire it. I'd have to look at the wiring diagram on my service DVD when I get home. (I'm at work right now) If you want I can e-mail you when I find out the wiring for it if you want. (I get off at 11:30pm and will be home at midnight)
