@Harold57,
There is just a solid strip of the birdseye maple with "SC 430" in the gold inlay similar to the one that says "Lexus" on the radio door. I assume those with navs have that inlay on the door that covers the nav. I will say this, they picked a really nice piece of wood for my dash panel... some tasty curl and of course lots of birdseyes. :D Initially, I was kind of shocked as I thought the nav system was standard. Kinda cool to find out that it's rare. ;)

How about a picture?

Thanks, Liquid... yep, that's pretty much it. :D Of course, mine has the light wood instead of the dark wood shown above.
