Salam,
I love my Vitz 2013 3rd Gen. I love its ride and heart says to keep running it. Off course, i can't do it as you know petrol is very costly now days 
During Vitz purchase, i came to know that we can install multimedia steering and Vitz Hybrid 2017-2019 speedometer in Vitz 2011-2015 3rd Gen. I got to know that it's plug & play without alteration. I hate alteration. Alteration destroys your wiring or mechanical system.
After Vitz i have purchased and installed multimedia steering and Vitz Hybrid. It's fact that it's plug & play. I have also got settings buttons of multimedia steering LCD which i will replace with phone buttons.
I have loved this change. I would recommend you too if you like to add beauty and convenience in your car.
