After searching TW for basically an entire day, wondering if it is possible for the 2012 and 2013 folks without the Nav / JBL option to keep their stock HU but still have Sirius / XM radio... But without getting that lame little second receiver thingy for sat radio, I finally got the answer!
So to all the newer Taco owners who like the stock look that want satellite radio, go here: http://www.tacomaworld.com/forum/2nd...een-radio.html

I found lots of other make shift / very creative ways, but this seems the most efficient / fool proof!
