What satellite radio replacement equipment do I need?

I have a 2008, package 6 Prius, installed an "Directed TOY-SC1 SiriusConnect Tuner Interface" which has now died. Tried reactivation to no avail. Not made anymore. What do I need to replace it? The language is different, some say I need an adaptor with the new radio, do I need all new wiring, do I need the complete Sirius kit that is almost $200? Or do I just need the tuner which is $51? Thanks for any help. Ray Sharretts
