Hi, I would like to upgrade my original CL9 head unit with after market like:

IS there anyone here got it installed in your car? As my understanding that the climate control of passenger and driver opposite with Australia model.

Can I installed it by myself just plug and play without any modifications of wiring? because I am not good at that. If there is any one got it please share exp with any problems.

Thank you.
