Help - terk in a Prius basic?

Help! Here's my tale of woe. After reading about the xm installation on a basic Prius ('07) I bought the kit and following Prius thread instructions, put it in my car. I checked it for signal and got SAT 1, SAT 2, etc. I buttoned the dash back up and got nothing. I took it apart again and checked all connections, etc., but still got nothing.
I decided it must be a faulty terk unit, so xmfan store let me send it back and replaced it. I again installed it (thinking about putting zippers in), but got zip, ziltch, etc. Now I'm thinking it might be the head unit in the car, but when I talk to my dealer and admit I'm putting in an aftermarket unit, they just stare at me and shake their heads. They say they have no way to test that plug in the head unit.
Any suggestions will be appreciated.

 

The radio works on all channels except the sat channels. When we called Terk they said it was not compatable with the Prius. I have cycled through the presets several times, but I'll go back and try again. Thanks for the replys.

 

Cycling didn't bring it up either. I have now ordered a kit through my dealer and it may turn out that something is wrong with the head unit, so we shall see. XMfan store would not take it back claiming if Terk doesn't list it as compatable, then I am SOL.

 

I cycled from AM to FM more than 24 times, disconnected everything, then connected and did it again for at least that many more times. I have given up on it. There must be a reason Turk does not list the Prius as compatable. So if anyone wants to try xm, Turk style, I'll sell this kit. I still think it might be a problem in the radio itself.

I am supposed to get a unit from Toyota Thursday and I'll let everyone know if it works. :mellow:

 

My dealer put in the xm addon, couldn't get it to work and then decided my head unit was not compatable. Since everything else works on the radio, they wouldn't send the unit back for warrenty because Toyota says it's not compatable. Oh well, guess I'll replace the Skifi unit I had before I got excited about integrating.

 

Not one to give up, I figured I'd give it one last try. My son found on the Toyota web page where you could "build your own Prius." He put in my car, and one of the accessories available was the xm radio. So I marched that down to the dealer. The first fellow I talked too just shook his head, said there was nothing they could do, so I asked to see the service manager. I overhead him saying "we don't want to waste our time putting in an aftermarket piece of equipment", so I asked to see the head honcho.
His tune was entirely different, and after I told him I had gotten pretty good taking the dash apart (I credit Priuschat for that), he said okay, and brought a brand new Prius with the same radio into the front end of the building. He asked me what tools I needed, and away I went.
Sure enough when I cycled through the modes, up came Sat 1, etc. So he swapped me radios and I now have xm. There had to be something wrong with the auxiliary plug (in) in that first radio.
Thanks to all who replied. The Terk unit does work in the Prius, basic radio, and if Terk had owned up to that it would have helped my cause.
Both Toyota and Terk said it would not work, but, again, thanks to Priuschat I kept pushing and now I have xm.
