I just replaced a 2006 Tacoma 4X4 Access Cab V-6 Base with a 2012 4X4 Access Cab V-6 SR-5. My '12 had everything I wanted but alloy wheels and XM radio. I added 16" TRD off road wheels (how much are the styled steel wheels worth?) and surfed the web a bit to see what I need to make use of the XM ready (has AM-SAT button) radio. The info I find on adding XM radio is a bit confusing. What is the best XM kit to buy for a plug-and-play addition? My '12 has no XM antenna, so I will need to add that as well.
