I took my car to the dealership, who initially quoted $1692k just for the part. I mentioned this forum and the fact that I found 45 complaints, regarding this issue, between this site and another Lexus forum site. I also mentioned that there was talk of a class action (on the other site) because there were so many complaints from owners of 2006-2008 IS and ES owners with <60k miles on their cars. The dealership offered to pay for 75% of the quoted price of the part. I walked out of the dealership with a brand new touch screen for $460. Still stings, but not as much as it could have. Also, anyone with this issue be advised that the screen itself and the nav system are two separate parts. Dealerships may try to convince you that you need a whole new nav system, most likely not the case.
