I decided to upgrade to Dudu7 and already purchased and in the process of waiting for shippment. My car already have Android Head Unit with the 16 pins power cord. My local mechanic installed the multifunction steering wheel and modified it so it's work on my car without canbus.
From my understanding, my mechanic should already wired SWC1/SWC2 to the power cord. So, when I swap the Head Unit to Dudu7, I just need to go to SWC to setup the multifunction buttons, correct? My car is Lancer 2006.
This is the power cord my mechanic installed to my car.
