2001 Lexus Ls 430 Navigation Update Disaster!
Brownize replied to davisnetworks's topic in 90 - 00 Lexus LS400
Hi all, I seem to have the same problem as the OP. I have a 2001 LS430 (love it!) and put in an upgraded disk and got an error message. So I put back the original factory disk and still get the same "Disk read error. Check disk" message and can't click the "I agree". I tried the negative battery method suggested and it started reloading for a few seconds and then gave the same error message. Any other ideas? ... besides a trip to the dealer Thanks
