I have an 05 tc and the audio system looks just like the others but instead of a sat button on the right side, it is a pwr button. It has no home button on the top right. I am looking to add xm radio and I dont no what is wrong with it. I bought this car used so I do not know what the guy before me did. Anyone got any ideas?

 

one suggestion, get a new and better head unit. the stock head unit is okay, but if yours is messed up, it ain't worth salvaging.

you can get the upgraded 6 disc in-dash player from scion, and a sat radio reciever for it, and get it installed, but it is rediculously expensive.
