Darryl still offers his services via ebay. He has done quite a few of our members NAV units on here. I even talked to him about doing mine; but I found a used, local NAV unit to replace my bad one.

So my touch screen stopped working today after 10.5 years of owning my '07 Lexus (Oct 2006 purchase date). When I press on the screen, the map just moves to the right. Based on my research, the digitizer is broken. So I'm going to buy a digitizer from eBay for about $24 and try and replace it myself. This is likely a heat related issue as it has been scorching hot here in Texas. Just a couple of days ago, my car was displaying 115 degrees for the outside temp, the hottest I have ever seen it. I do wish Lexus had made these sturdier or had issued a recall notice as it seems to be a pretty common problem. I'm still getting recall notices for other problems and this should have been one too.

Lexus didn't make the LCD screen components. I believe it was Toshiba. If the new digitizer doesn't work out for you, you can always replace the entire screen, which includes a new digitizer.

Amazon Amazon

Only $36 currently. I bought mine a couple years ago for $44 from Amazon. It's still working and a hell of a lot cheaper than buying a whole new head unit, which is what Lexus says you have to do at $1,200.

Disassembled the enitre NAV unit today and removed the old digitizer (a very challenging task), then I put on a new digitizer I got from ebay advertised as being for the 2007 Lexus IS, 7.3". It fit perfectly, the touch issue is now resolved, but there is a terrible rainbow effect. After reading some reviews, it seems this is a common problem with some digitizers. Has anyone had this problem? Is there a way to fix it, like by placing a special screen cover over the screen? Or is the only solution to find an OEM or closer to OEM digitzer.

Most of them will have rainbow effect. However, some of them won't have that problem but I don't know the seller name. Is your as bad as this one?

Yes, mine is just like that. The screen is much harder to see especially in the sunlight. I am currently looking to replace it.

The seller on Ebay is telling me that I left one of the protective covers on. I can't recall if I took both of them off or just one. Is it possible that leaving a cover on would cause this effect? It's gonna be a pain to open it up again.

You are probably right. I will order a non-rainbow digitizer before I take everything out again.

Default 2007 lexus is350

Hello everyone,

My navigation screen suddenly went full white. All the buttons and radio still function. And when I touch the screen it gives me feedback and makes the sound that I'm clicking something. But the screen just stays blank white and I can't see anything. This is a 2007 Lexus IS350. Any ideas?
