Hello all,
I own a 2011 Ls460.

There are 8 buttons alongside the navigation screen, 4 on the left and 4 on the rght.
They should all be illuminated when rhe lights are on.

The left side is perfect.
The right side, from top to bottom, passenger, map(voice), dest, info(phone).
The top 2 , passenger and map no longer lite up. Dest and info still do.

Are there small bulbs behind the buttons?
How do you remove the buttons?
Can i do it or must i go to the dealer.?

thanks
