Hello all. I am new to this forum and though this is my third lexus, I have just moved into the LS territory for the first time. My 2005 LS430 is practically flawless aside from the blank navigation screen. Now what seems odd to me is that the monitor works just fine when I hit audio, options, and climate. But when i push the menu, navi, or destination, the screen remains back lit and blank. I would appreciate any advice/info anyone has to give. Thank you, and I look forward to enjoying and participating in this forum with you all. Good day gentlemen...... and ladies.
