Yes he may have a CIC but one with a screen built after 07/2013.
This is the screen before 07/2013:
65509266385
And this is the on after 07/2013:
65509289008
So this DIY is only for those after 07/2013.
I you have a 10" screen built before 07/2013 (like me), you can't do this retrofit, or you have to change screen
