2004 LS430: navigation touchscreen issues (need help w/ replacement)
Hello, I have a 2004 LS430. The navigation touchscreen has been acting up for some time now. It seems part of the touchscreen is like 'dead'. I will try to push on an area but it is not responsive. Also the screen will not click on where I actually touch. Another issue is, sometimes, the screen will randomly click by itself.
I want to fix this issue, and have been looking at replacement parts on eBay. But I'm not exactly sure what needs to be changed. Of course I only want to change just enough to get me a fully functional screen.
Do I need to swap out the whole navigation unit, or can I just change the 'LCD display'? Also, does anyone have any guide (with pictures?) on how to disassemble the dash to perform this task?

I have an 04 and had temperature related display problems (took up to 5 minutes to work). If you do a thread search in here (use Nav display repair), there is a lot of info. Same also if you Goggle "LS430 Nav Display Repair". There are detailed instructions if you want to do the repairs yourself.
There's a So Cal company called "hitechserv". Can ship the whole unit to them. Worst case repair cost approx. 650. eBay purchase gets a display w/ no history, no guarantee. I found someone local and had them re solder all connections on the display unit circuit board. It was cheap (150 total) and it works.
Good luck.

Do your research thoroughly as you don't want to spend big bucks to still have problems. I have found that the first series 2001-2003 have had few issues with the Nav on this forum... other than water leaking into the trunk area and affecting the reader. Not that many Nav's for the very early LS430s have issues. Make sure you have diagnosed your problem correctly before proceeding. Good luck and let us know how you made out.

Hello,
I thought I would provide a small update. The touch screen would work at times, tends to be when the weather is colder. I found a complete replacement unit for relatively cheap so decided to buy it. Swapped it out and now the touch screen is working fine. I suppose there might be a loose solder inside the original unit.
