I purchased a used 2010 Fusion SEL AWD last October. It has the Sony Premier system but no navigation. I finally got the itch to change it up by installing my old sub and sub amp from my previous vehicle. That has grown into purchasing a Pioneer AVIC-5200NEX HU, 4-channel amp, speakers etc. The last parts I'm waiting on are the Maestro Rr and FO1 installation harness. My question is... do I need to purchase the $70 Sirius kit for the tuner module? The factory unit has Sirius, which I use, and an antenna (obviously). Is the tuner built-in or separate? Thanks
