I have a 2004 LS 430 w Nav/ML sound, just out of warranty. My touch screen started acting up, highlighting about an inch or so to the right of where you touch. I took it to the Dealer who found what appears to be a small line or crack starting at the lower left edge of the screen running up diagonally a couple of inches. You could not see it from the driver seat, and have to get the light angle just right. The crack is not in the top glass screen but appears to be in another layer underneath. The car has never been in an accident, and I'm at a loss as to how the screen (especially the "under" screen) could have been damaged. They quoted $6,500 to replace the entire navigation unit. I've found a couple of places on-line that say they can repair or replace it, but I need to find removal instructions and send them the unit. Does anyone know, can you remove the Nav Screen without taking out the entire radio system? Also, will the car operate without the screen? I'm still searching for solutions. Any help would be greatly appreciated.

There are several places that sell XM Radio and Ipod interfaces, and they can give you some assistance with removal. Try "vaistech.com", or "pro-fit-intl.com" Good luck!

Did you find a solution? My 04 LS 430 just started doing the same thing. It was working without any problems, then it started where it would light up a buttom to the right of what was touched. Mine is just over 50k/48 mos.
