I've been wanting to do this for quite some time now but with different switches. Unfortunately, instead of the sunglass holder, i have a non-functional "lexus link" in that location. I've been trying to source either just the sunglass holder (which i don't think is possible) or an entire unit with homelink.
So far there are a few things I will do differently when I add the other switches and 6-switch panel up there.
The way they are now you can't read what the switches are without contorting around. If they were flipped 180°, they might be readable. Also, the mounting height makes the led's in the switches visible in the rear view mirror. I'm hoping to angle the switches to the rear of the vehicle instead of being flat with the roof like this: ---- they will be more like / except maybe closer to 15° from flat. Kinda hard to put in to words but I just wanted to put it out there for others to definitely give it some thought, at night, with the switches lit up! The reflection in the mirror can be masked pretty easily but since I have all the parts to do the new switches I am leaving it all alone until I can rework the whole thing.
Also of note, that area is a little more shallow than I thought it would be.
This is my switch setup, just need time to wire it up and install it:
