Hello,this is my first post.I want to install Sirius XM in my 2.5i Legacy.The radio is a basic single CD with no Nav or Bluetooth.I can get an Onyx from XM or buy a kit from the dealer for $398.00 plus install.I`ve been on craigslist and EBay and found out 2012-2014 Clarion/Harmon Kardon radios are XM ready but will not fit my car.(different faceplate,wires,antenna etc.) and my Panasonic needs either the expensive upgrade or the Onyx.What are my options? I`d like to have a clean fully wired radio for satellite but don`t want to pay over 400$.Any information and prices on other options would be greatly appreciated.
