Head unit wires question
 

Hi!

I own a 2010 Lancer Sportback Ralliart and looking to replace my head unit to Dasaita Android 9.0. My plan is to install the hand-free buttons on my steering wheel and to install the hands-free microphone in the roof. But my main concern is how I can use the hands-free microphone instead of the one that comes with the new Dasaita unit? I guess I can tap on to the microphone wire and install a 3.5mm plug at the end, but how do I find the other end of the cable that comes from the roof microphone? The Dasaita unit has a 3,5 mm input for the microphone.

Do I need the bluetooth module too for the hands-free controls to work with Dasaita?

I also want to use my pre-installed AUX ports to the Dasaita unit and need to locate the other end of that cable too. How do I find those cables?

I have read thru the manual but the wire manual is hard for me to understand. I attached them here so that maybe someone can see if the can figure it out for me. :-)
