2007 Sirius Install questions

Hi All,

Not having much luck with the search function finding what I am looking for. This weekend i'm going to tackle the SCC1 and TOY-SC1 install for my 2007 Prius. I have a few questions, can someone tell me how to run the antenna to the roof behind the radio antenna, under the carpet, through the roof, etc. If anyone has a document that would help me I would greatly appreciate it. Also is there a document to assist with the install? Especially accessing the back of the stereo to plug the cable in..

Thanks a bunch,

Greg
