I picked up my 2007 Mazda3 yesterday, I was all excited about hooking up my iPod to the auxiliary port when I saw this little sticker saying it is disabled due to satellite radio being installed. After doing some research I found I need a $150 switch box, is their a way to just completely disable the satellite radio since I do not use it and only have the auxiliary port working without paying the $150 for a switch box. Would this be simple enough to do at home? Thanks in advance for any help.
