I posted this in the 5th Gen forum and so far....not a response (89 views though). This is my cousin's car. I thought maybe some of you here in the 6th Gen forum previously had a 5th Gen and may have experienced this and can help?

08 ES350 that the Nav doesn't work.......screen goes white and sometimes can see the location icon but mostly just white. The BU Cam, radio display, and climate controls all display as they should. Lexus dealer said to replace the Nav screen for about $2000 (or salvage part for about $1000) but that doesn't make sense to me because the other functions seem to display on the screen just fine. Any thoughts or suggestions. Seems like something driving the graphics for the Nav is just loose, missing fuse, or something like that. Not sure where to start.

Thanks!!
