Crutchfield calls it a FM DIRECT ADAPTER.
From what I read, it's a vast improvement over the fm transmitter because as least you are not transmitting through the air with all that interference.
For $19.99 it seems like a relatively easy way to get sirius to sound at least better than transmitting. Since I have gotten sirius for my wife, she can't really enjoy it to much because here on LI, there is just way to much interference.
Since I have to take the radio out to get to the back, is an aux input device is just as easy since I have to get to the back of the radio anyway.
What parts are involved for the corolla so I can do this input device thing?
EDIT: how about this, would this work

Thanks
