I found this video along with instructions on how to ovewrride the Navigation sysytem.
Has anyone tried this and has it worked?
Car Tip: Toyota/Lexus Navigation Override
Quick video showing how to operate the navigation & phone system override in many Toyota and Lexus vehicles. Once the Override is activated, the nav system and phone system can be operated while the vehicle is in motion. The system returns to its default settings each time the car is started.
Step 1 Press The Menu button
Step 2 Press the Volume button
Step 3 Press The Upper Left of the screen
Step 4 Press The Lower Left of the screen
Step 5 Press Upper Left of the screen again
Step 6 Press Lower Left of the screen again
Step 7 Press and hold the Override Button until system beeps
Step 8 Press Back Button in upper right corner
Done! The Buttons For Navigation & Phone are now accessible
Older Lexus and Toyota Systems may require a slightly different process:
Step 1 Press The Menu button
Step 2 Press the System button
Step 3 Press The Upper Left of the screen
Step 4 Press The Lower Left of the screen
Step 5 Press Upper Left of the screen again
Step 6 Press Lower Left of the screen again
Step 7 Press The Lower Right of the screen
Step 8 Press and hold the Override Button until system beeps
Step 9 Press Back Button in upper right corner
Done! The Buttons For Navigation & Phone are now accessible

Tons of threads about this topic. The upper/lower/upper/lower etc trick only works on nav dvds v5 and maybe earlier. it was a hidden diagnostic menu used for several purposes that got out to the general public. primarily used as a way to unlock the nav. So when Lexus published dvd v6, they either removed it or hid it differently. and it's never been cracked since.
there are a lot of threads on burning homemade dvds that mix the override trick with newer maps etc. and some after market gadgets like lockpick that will unlock the system while in motion.

I wasn't aware there was a gen6 but maybe there is. I thought the latest was gen5 ("genx" designates hardware I think). My 06 GS has Gen4 nav and will always be Gen4 no matter what dvd version i put in. Maybe we're both referring to the v6 dvd. What I meant to say was on the software side, dvd 5 had the secret menu but only dvd v5-no others. v6 didn't have the menu but could be hacked with homemade version of the dvd. v7 is locked down so even that won't work and cant be hacked without a wiresplice or after market kit. Lexus is really cranky about the nav input in motion thing. Liability protection no doubt.

you need a copy of both v5 and v6. you take the loading.kwi from v5 and all the files on v6 EXCEPT the loading.kwi and burn the blended set onto a dvd+r DL (double layer) dvd. you end up with v6 maps and v5 loading.kwi on the same dvd. the loading file is where the hidden unlock menu is.
You can pick up a v5 dvd on ebay or craigs list pretty cheap since it's old. you need that for the loading file. just be sure to get v5 dvd for the Gen type of hardware you have.
first step is to figure out what dvd version you have. easiest way is to eject it and take a look. I don't know where the nav dvd player is in a Highlander but the manual will have it. 2nd is to be sure what version of nav hardware you have. 08 would have Gen5 i would think but a quick call to the dealer parts dept should solve that one.
you can combine v5 and v6 dvds for any Gen of nav hardware and it will work. combining v5 and v7 won't work for Gen4 hardware. I know that for sure. Other posters say they have gotten v5 and v7 combo to work with Gen5 systems.

I haven't tried to reverse engineer something to remove the I Agree so I am not 100% certain of this but i really doubt that you could remove I Agree by simply removing a file. I think it's embedded in the loading.kwi file and if you remove that, the system wont work. As for manual bypass with gen 2/3 I think you'd have to get a dvd ver 5 and try it unless someone has already done that. Hopefully they will chime in on that piece soon.

If I understand what you have, it's a gen 2 or 3 nav system. For gen 4 or 5 systems you need the loading file from dvd version 5 coupled with the maps from dvd version 6 or 7. I don't know if that will work on the gen2 or gen 3 systems. You might research the forums for older IS and GS cars. Some of those would have had the same gen 2 or 3 nav systems as you car I think. you might find info there that applies to your navi.

why don't we pitch a ***** we Lexus and tell them what we want in a Navigation system? We are the one buying the thing if its not what we want then tell them to fix it the way everyone else has theirs.

agree with you. if you read the G and L model threads, you'll see a lot of venting re navi as well a lot of energy to work around the limitations. Unfortunately, I don't think Lexus is listening or cares. Their lawyers have the upper hand on this one it seems.
