Howdy all. New to forum, been searching for hours without finding what Im looking for so if this has been answered elsewhere, forgive me. I have a 2012 Frontier Crew SV with the 6 disk factory head unit. Im wanting to replace this unit with a Pioneer AVH-200EX that has backup camera. PLEASE someone tell me there is an adapter that will work with my system that will retain steering wheel controls. I don't really care about keeping the XM radio. Thanks in advance!!
