Sonartech Sir,
Can I groud the yellow parking brake wire pin23 (from plug end) to pin10 for ground? When I bring the car in for dash rattle, and tech dismantle my dash, I don't want them to see a wire stick out from the hardness to some other grounding point.

Sorry Sonartech,
I wasn't clear enough. I was referring to your wiring information in post#154 for GS350. The plug is K46, cutting the yellow wire, then plug the end from the harness plug to pin 10 for ground. Can I do that?

Here is another way to burn a new DVD with Generation 5 Version 6.1 maps and the Version 5.1 LOADING.KWI loading file. My thanks goes to this forum and especially Sonartech. I had a lot of trouble getting it to work but finally it worked. Below is a detailed description on how I did it.
HOW TO ENABLE THE GRAYED OUT NAV SYSTEM FEATURES WHEN DRIVING
We have a new 2007 ES350 and I really disliked the fact that the NAV system was “almost” unusable when driving. Who wants to stop so your wife can enter a new address into the NAV system while I am driving…yuk! This “non invasive” fix will allow using all the NAV system features when driving. The fifth paragraph from the end tells you how to remove your current NAV DVD from your car.
With what I have already read on this forum I was able to fix the Version 6.1 NAV maps DVD that came with our 2007 ES350 by modifying the DVD only. No removal of the NAV head-unit itself and no wire cutting. If you’re interested here is a detailed description on how I did it. What is new here is that I did it using Roxio Easy Media Creator 9 and I have found another burner that will burn this specific double layer NAV DVD. This should work on any Generation 5 NAV system.
I burned a dozen disks learning so here goes. Not all DVD media works. The DVD that I know works is: Memorex DVD+R DL (Double Layer) 8.5 Gbytes, 240 min, 2.4X. Do not use Dual Layer. Dual Layer is a DVD-R, don’t use it. I mention this because these Double Layer DVDs cost $1.80 plus each so no need to waste them.
Not all burners that can burn double layer DVDs work. For example my D: CD drive and my external Memorex Double Layer 16X DVD + - RAM 510L v1 would NOT burn this NAV DVD correctly. Finally, I bought a Pioneer DVD-RW DVR-K14RA for my laptop’s D drive because my wife’s laptop had that specific burner and it burned a workable double layer NAV DVD. This Pioneer model works. The only other burner that I know of that works is a NEC ND-3540A. If yours will not work using the above media you’ll have to buy a new burner or use a friend's double layer burner.
The NAV disk that came with my 2007 ES350 is a Generation 5 black colored DVD and it says U31 D on it. Next put this Version 6.1 disk in you your burner and drag and drop the all the folders and files into a new folder on your PCs fixed disk. It may take 40 plus minutes because you’re moving approximately 7.3 Gbytes. Make sure ALL the folders and ALL the files are copied to your PC, count ‘em. One of my failed disks was because one file was not moved over.
Next you must already have the file LOADING.KWI 46,956,000 bytes from the Version 5.1 NAV DVD. The Version 5.1 DVD is black and has U30 D on it. You’ll have to find a friend or someone that has a Version 5.1 DVD. If you’re going in for service you might ask for a loaner with a NAV system. Who knows, it may have a Version 5.1 DVD in it.
Here is when you will remove the Version 6.1 LOADING.KWI file (71,684,000 bytes) from the folder on your PCs fixed disk and replace it with the LOADING.KWI file (46,956,000 bytes) from the Version 5.1 DVD. Yeah, it’s a few fewer bytes but so far I have noticed NO problems or loss of features using the version 5.1 instead of the Version 6.1 loading file. On the other hand, if I encounter serious problems in the future I’ll just reinstall the original Version 6.1 disk that came with my 2007 ES350. So far, using the Version 5.1 loading file, we can enter addresses, POIs, and all those other NAV features that used to be grayed out when driving. It’s Great!!!
I used Roxio Easy Media Creator 9 to burn the DVD. Sorry, I do not know how to do this using NERO. Start Roxio 9 and choose DATA and then DATA DISK. Use the Roxio command ADD DATA to move the folders and the files from the folder on your PCs fixed disk to Roxio. I first added the folders and then the files. Double check they were all added. Check that you removed the V6.1 and in its place have the V 5.1 loading file (LOADING.KWI). Now choose OPTIONS (lower right corner) and use the following:
TYPE: Track at Once (TAO), Open
Mode: Mode 1
File System: ISO+Joliet (106 character file names)
Choose the BUTTON that says, “I only need to use disks for one recordng, etc.”
Checkmark, Verify data written to the disk after burning.
Click on OK to go back one screen.
Read the lower left corner to make sure the DVD symbol says, “Estimate 7.3 plus or minus.” All this tells you is that the burner expects a double layer DVD.
Last but not least, try to notice when it starts whether it is burning at 2.4X which is the Memorex DVD media speed. It will be.
Finally, click on the BURN symbol in the lower right corner and go get a coffee, lunch, and dinner because it takes an hour to burn and verify a 7.3 Gbyte double layer DVD.
Once you have the new DVD go to your Lexus and try it. To install it first disconnect the negative battery cable for 5-7 minutes. This is supposed to kill the NAV system memory, loading file or whatever. Actually I don’t have a clue what this does but I was told to do it this way and it worked for me. Don't forget to reconnect the battery cable.
Now go into your Lexus and press the start button once so the car is on ACC (don’t start it). Press the MENU button to the right of the screen. Touch “Map DVD” in the upper right corner of the screen. Touch DVD in lower left corner of the screen so the current DVD will come out. Remove the current one and insert the newly burned DVD. On mine I had to push the DVD in a bit, very gently, so the changer would finish pulling it in.
BEWARE: you’ll probably get a screen that says to see your dealer and some Japanese characters below it but be patient. The loading will start within 20 to 40 seconds and your heart will again start beating at its normal rhythm. If it flat out says CAN’T READ DISK, the disk probably did not copy properly but wait another minute or so anyhow. If it does not burn properly it is probably the fault of your burner. Try someone elses!
After it's loaded here is how to UNLOCK the navigation system features. The following can be done either when you’re parked or driving so you do not have to do this before starting to drive.
To enable all the NAV system functions that were grayed out because the car is moving do the following:
Press the MENU button to the right of screen.
Touch VOLUME at top center of screen.
Touch Upper Left Corner of screen.
Touch Lower Left Corner of screen.
Do it again…
Touch Upper Left Corner of screen.
Touch Lower Left Corner of screen.
A service menu will appear.
The bars are black but turn turquoise when you touch any bar.
Touch and hold the OVERRIDE bar until you hear a beep (about 6-8 seconds).
When you lift you finger from that bar it will turn BLUE, you’re done.
Touch the Upper Right Corner of the screen to close the service menu.
Then press the MAP (voice) button to go back to the NAV map.
You can now enter addresses, POIs, and so forth when the car is moving and you also have the latest Version 6.1 maps, POIs, and so forth.
If you turn the engine off you must do this again.

Here's my checksums for the U31D v6.1 LOADING.KWI with part number ending with 2 instead of 0:
DVD PART NUMBER = 86271-53021, 464210-0792 (note-ends with 2 instead of 0).
- CRC32 = $81F9F13E
- MD5 = $4F6E0CC9AA983B4A8A63611BCAED0232
- SHA1 = $D06350082CBB7F84C9981B7F5C6DD4F5948CA4E4
In any case, the hybrid DVD worked on my 2008 Lexus RX350 with the v5.1 loading.kwi (version/checksum) same as SonarTech's post.

I believe that almost all loading.kwi files will work in all Toyota/Lexus vehicles...
I've even used a loading.kwi from a toyota camry hybrid in my car and it worked just fine...

Ver 6.1 diagnostic screen
Sonartech,
You probably already saw this but here is a way into the
5th Gen Ver 6.1 NAV DVD. See attached photo.
I saw the set of steps to get in somewher on one of the the forums.
The empty spot is probably when the OVERRIDE originally was in the Ver 5.1 NAV DVD.

GS350 6.1 Nav Hack TIps
You can follow the directions for the Nav hack on this thread, but be aware that the location of the h1 plug is different than the GS300 version. The plug and wire to be cut is completely different also.

Regarding the NAV hack at the top of this thread, it works while the car is in motion. I tried it on my 2005 GX470 and it works great! Thanks you!!!!!!
