I have the same problem like, other that like to explore new thing etc. First of all thanks to all people who try to fix the problem, post their messages etc, without the information I think I have to spent $300 or more to fix nav. I have RX 330 2004 Gen Nav 3 one-piece nav ecu, no rest button. I have done this before I fix the problem. Remove battery (Neg), ECU Battery, Use Gen 4 NAV software etc still not work until I did this step. 1.Bit Torrent 6.1.2 software download and install 2. Search for Toyota Lexus Navigation DVD Gen 3 3. I download the file Toyota Lexus Navigation DVD Gen 2-3 v7 when done the file should be Toyota Lexus Navigation DVD Gen 2-3 v7.1 86271-33036 464210-0930.rar 4. Extract the Toyota Lexus Navigation DVD Gen 2-3 v7.1 86271-33036 464210-0930.rar 5. You should have lexnav.iso files size 8,093,184 KB 6.Download SetupImgburn_2.4.2.0.exe 7.Install the software 8.Run the Imgburn. 9. I select write image file to disc 10. Select the source ( Lexnav.iso) 11. Select destination drive 12. Configuration write speed ect. under Settings I click change Book Type icon Under Change Book Type menu I select Samsung ( that I have on my pc DVD+R DL) Under Samsung is gone ask Change for: I select Drive ( for DVD+R DL Media) than under New Setting: I select DVD-ROM, than click Change icon “Success” click ok! Under Change Book type Click OK to exit. 13. Write Speed I select 2x 14 Now I click write Icon. I Use DVD+RDL TDK Brand 8x speed. When the burn is done. I start the car up and take out Nav disk I burn before, that not work. While I take the disk out the screen is still in Japanese etc.. Then I put the new one in (unit door still open), the screen is the same like before. I turn off and start up again the system went into update mode and error out, went back to the old problem. I turn off the car then start up again this time the system say” something DO NOT POWER DOWN SYSTEM ….and then about 5-20 second HAAAAA the system went back English screen. I test driving around the map look better I did not check other NAV function yet, but I am so happy this is working I thought I have to buy I nav system. Again after this I do not want to find what is in the secret menu. If anyone have the same problem either buy the update Ver. With same Gen or do the above step. I hope this information will help who have the same problem like I have. Sorry about grammar is very bad. Good luck!

Never drove with it removed but did turn the key on with it removed, nav screen worked for a bit and buttons were not there like when the amp wasn't working, further proving that the amp was the issue. Then either when I restarted it or turned the key off and on the screen was completely dead, nav, lexus link, etc... goes through the amp. I did not check the Climate controls when the screen was dead to see if I could get into them, but that might be something that you would have to deal with until getting yours back. Someone else might be able to tell you for sure. Hi, Any closeout on this. Did your new amp fix the problem. I have the exact same issue on my '03 ls430 with ML and nav. Thanks
