The other thing I noticed was that my Aux-In jack itself had a model number of 86190-02020. I'm not sure I've ever heard of this before - if anyone is pulling out their storage compartment to install a VAIS or something like that, can they check the model number on their Aux jack (it's on a sticker on the plastic housing sticking out from the back of the storage compartment), and also confirm whether there are four or five wires coming out of it?

Thanks!
