Pac Audio makes the SWI-JACK that should work with any kenwood unit that has a wired remote input. Though, reviews of this part indicate that you may have to hold the buttons a little longer for it to respond. I used an SWI-X which is an infrared version of this and it didn't require me to hold the button, but had a half second delay between when I pressed a button to when it would send the signal. It's the only solution I am aware of.
