:confusedHello everyone. I have an 03 IS300 with the factory flip out Navi. im changing all the orangish bulbs to LED white. my problem is where do i start to take out the climate control dash? having factory Navi. All the DIY ive seen everybody just has the tray and there are two screws there, (no screws with Navi). and if you can answer this too, has anyone changed the Navi buttons behind the shifter, know the bulb sizes?? Thanks
