Adding aux port to 06 radio?

[Blackshadow2804]

Hey guys, I just got an 06 2500 with the upgraded FM/SMX/CD Changer and I'd like to add an aux port to it so for now I can avoid replacing the entire unit...

I found a thread from 2011 that said PAC made one, but now it's been discontinued and I can't find them anymore.

Are there any other options you guys know of?

Thanks
