*edit* See post #6 for Pinout / Diagram Here is the story... I am swapping out the factory Nav in my 2013 EX-L for a Premium Sound Nav. I plan on using an external 5 channel amp to power the interior speakers and also add a sub to the factory location. I am currently gathering all the parts for this project and managed to grab this headunit off ebay for a very reasonable price. Does anyone have a diagram / pinout for a 2013 Premium Sound Nav headunit? This is the one in question I searched the forums and googled quite a bit but could only find this diagram and corresponding pinouts. It doesn't exactly match up to the headunit in the photo above so I want to make sure that everything is correct going forward. I dont want to cut into the factory harness so I picked up a set of oem premium sound plugs from a harness off ebay but the 8 pin plug which is supposed to be for the sub output doesn't match up to what I have. Here is a pic for reference. Does anyone know where I could get the correct plug? Many thanks in advance.
