Auxilary interface

Has anyone used this ( honda / acura 03 Auxiliaryintface ( Care2Aux-Hon1 ) In Dash PC - Honda Acura 03+ AUX adapter (direct digital interface) (http://indashpc.org/new/aux_adapters/car2aux-hon1.html) . I am looking to put one in or have someone put one in for my Stiletto 2 ... If anyone has one what is the best location for it. Thanks

Good question, I wonder if it will work for my Sirius radio?? Was going to use FM antenna adapter plugs with a FM direct adapter.
