I have a kind of odd question. I like the look of stock equipment when it comes to the interior of my truck and want to keep it that way. That being said, I want to upgrade my head unit. I have a 2012 base model tacoma. My question is, does anyone know if it is possible to swap in the new 2013 touchscreen without hacking my wiring harness to bits? Another option I was considering was adding the factory satellite radio however I can't find any concrete information on what all I would need to do. Any info would be greatly appreciated.
