Hey guys. Newbie here.

 

I recently purchased an avic d3 and am a little lost as to what harnesses I need? I have searched this forum and lx platform specific forums and the answers are all over the place. I have an 06 chrysler 300c with factory navigation, boston accoustic speakers (w/center speaker on dash). I would like to retain stock steering wheel button controls and don't care about satellite radio.

 

From what I have read, I need three different harnesses to do the install. My question is, which ones exactly? Also, what would you recommend between pac audio and metra? Sorry for the newbie questions and thanks for looking.
