New Aux Input Splitter I found...

[Brandon Fuller]

Hey all, I know that adapter does not work but the PAC web site says they are working on another one that will. Its right on the home page:

AUX-GM24 Auxiliary Audio Input for GM vehicles coming soon!
The AUX-GM24 is a standalone auxiliary input for most 2003-2004 GM vehicles. Unlike our AAI-GM12, the AUX-GM24 works with vehicles that do not come with factory XM, factory DVD or factory external CD changer. The AUX-GM24 will have two auxiliary inputs selectable by the headunit's button. Even works in most vehicles with the factory 6 disc in-dash head units. The AUX-GM24 will come with some cool features not seen in other manufacture's auxiliary inputs. More details and vehicle application guide coming soon
