Welcome to TYF from another Chris, 2 hours east of you in BR and thanks for offering your experience!
Since you offered, whatcha know about Mitsubishi? I have a Kenwood DD to go into a 2011 Outlander Sport- 6 speaker system, no nav or Rockford Fosgate system. I believe that, on this level, it can be viewed as a Lancer. I have the Metra dash kit and harness and an Axxess ASWC-1. The factory radio has two harness plugs going to it and it looks like one is the basic power and speaker circuits and the other is the USB, AUX, microphone, etc. circuits. I am not finding solid info on where to get the car's data wire to connect the ASWC-1. Best I've found is the steering wheel control wires are in that other harness. I'm fine with cutting and tapping into them, just need to know what's what.
