Yeah, I ran into the Lockpick C8 reading various Dodge/Chrysler enthusiast forums, and that would be the ticket for getting a nice aux input that I don't have to pump through the headphone jack on the front of the factory unit (among other nice things it adds.) It'd be absolutely perfect if one of the things it gave you was an audio *output* for the factory system -- then I could just pump that into my empeg's aux input, set up the cellphone mute == switch to aux behavior, and I'd probably be in good shape.

Of course, this whole exercise has hit a bit of a snag, as the upcoming model year changeover at the factory means dealers aren't taking new orders for 2012s now, and no dealers within 300 or so miles have the car with the color/options I want. Hopefully the 2013s don't have an even worse situation going on with the factory system...
