Audio Systems: 07 Corolla / Sirius FM Direct Adapter, sirius starmate 4, bad reception

Question
Can you help me. I recently put a Sirius Starmate 4 in my wifes 07 Corolla and the reception is all fuzzy. I want to install the FMDA25 wired relay adapter but dont know where to put it. I don't want to open up the dashboard or anything. Might there be an access point near the trunk or anything? Thanks in advance.

Answer
you need to  open the dash and remove the radio  it is not that dificult and nothing is going to get damage  the bad part is that the bad reception and fuzzy audio are going to be the same this is what you need
