what's up guys, so I attempted to do the nav hack on my car and I found that the wiring setup was different than the one shown in the DIY thread here :

I have a 2013 IS350 F Sport non ML but I'm able to play DVDs when the parking brake is engaged.










the DIY says to cut the pink wire and the white wire with silver paint.
I found the pink wire no problem but the white wires have a thin black line no silver,..
can anyone confirm these white wires are in place of the previous white with silver?

thanks for the help
