Congrats..... Thats the SUV that got the Green People to scream at Toyota for making such a monster of a SUV. The Tundra (which yours is based on) also has Green People screaming. I actually like the Sequoia, well not the name, but the SUV itself. Its what the Dodge Durango should have been. If I wasnt such a die hard Dodge fan, I would consider the Sequoia.
Why not have the screen fold out the top of the dash were that clock is? i guess you would have to figure it out, but I cheated and decided to add enclousures and motorized screens that open up ontop of the dash. In your case though, you have a huge dash and you may be able to have the screen stationary on the top of the dash, you have the room so use it!
