Navi Update to V15A8910 skip the dealer
For those technically incline and want to skip the dealer, I found the latest update to our navigation units online. The latest version is V15A8910 based on the TSB here:
http://www.revbase.com/BBBMotor/TSb/...dPdf?id=197088
The firmware itself can be grabbed straight from Lexus here:
https://dl.securedp.toyota.com/lexus/entune/13LHENNA-AA01_0004.kwi
Quick steps:
1. Download the above file. Take a USB key and format the key as FAT32, MUST BE FAT32!!!
2. Plug the key into the car, start the car (as in leave the car running)
3. Go to General Settings then down to Software Update, finally Update (NOT Gracenote update)
4. The screen will show you your current version and give you the option to proceed with an update if one is needed, if one is not the update button will not be enabled
5. Update takes around 5 minutes or so, leave the USB key plugged in and follow all the instructions.
6. Enjoy skipping the dealer for updates
This firmware update applies to the GX. Just verify your firmware version is following the similar scheme as V15AXXXX

Trust me my link is correct. Following LexusDrivers points to an older version. I know the filenames seem funky but my link will get you 8910 (the latest)...8872 is not the latest (LexusDrivers link).

Can One update NAVI for GX460 2011 using this method?
If yes where is the USB port located for updating NAVI to the latest version?
If not anyone knows how i can update 2011 GX460 without going to the dealer?

No, you can not update Navi maps via this method AFAIK.

Your link shows the file for download is ***0004.kwi but when you click on it the actual file to download is ***0003.kwi.
Why is the different? Thanks.

Lexus lists the 2010-2013 GX models as dealer only USB updates. Whether there is a workaround I do not know as I have not come across anyone who has done it successfully.
