With this secret menu you can see any fault codes, test all the panel buttons, turn on the rear camera and look at Nav data. I'll post some pics in a few days. But, for those of you that can’t wait to try it I'll describe it. *NOTE* This will lock you out of the radio controls. Attempt at your own risk!

I have a 2004, 3rd gen NAV running version 3.1. There is an easier way to get there then how I will describe it below but this is the easiest way to describe it. Here is how to get to the secret menu:

- Press INFO button and then "Trip Information" (This is to bring up a background to give a reference for where the hidden buttons are. Once you know where they are you can delete this step)
[attachmentid=5634]

- Press DISPLAY button
[attachmentid=5636]


- The hidden buttons are the A in "After Refueling” and the C in "Cruising Ranging." Press A and C in the following pattern. A,C,A,C,A,C. (That should be it, but just keep going until the menu pops up)
[attachmentid=5635]

- The Service Menu should appear. The only thing I wouldn’t mess with is the Memory Copy and paste stuff.
[attachmentid=5637]

- While in this menu you can also monitor trouble codes. Once the system has done a self check all the buttons at the bottom of the screen will turn blue indicating that you can select that option. To check all active trouble codes select LAN Monitor in the lower left corner. The screen should appear.
[attachmentid=5638]
To see the trouble codes push the CHEK button next to the system that has a CHEK button availble. If the are no faults/codes them the button will say "no err" and you wil not be able to select it.

- To get out of the menu press and hold DISPLAY button for 4-5 Seconds. Normal screens should appear and the radio controls are released. If that fails turn off the car and restart.

For those that don't know how the GPS override is done. This works for Gen 3 version 3.1

1. With car on, in PARK or fully stopped, press MENU.
2. Press DVD (upper right corner)
3. There are hidden buttons on this screen. Use the fat part of you index finger not the tip for best results. In order press
a. Upper Left Corner
b. Lower Left Corner
c. Upper Left Corner
d. Lower Left Corner
e. Lower Right Corner
4. You should now see a screen with 2 columns of 4 buttons. Locate the GPS button
5. Press and hold for 5 seconds. It will beep one and then turn green
6. Press the BACK button in upper right hand corner
7. Now you can use all the NAV functions while in motion. When you turn the car off the NAV will reset to normal and you will have to do this procedure again when you restart the car.




For Gen 4, version 4.2:
1. With car on, in PARK or fully stopped, press MENU.
2. Goto the menu that controls volume functions
3. There are hidden buttons on this screen. Use the fat part of you index finger not the tip for best results. In order press
a. Upper Left Corner
b. Lower Left Corner
c. Upper Left Corner
d. Lower Left Corner
4. You should now see a screen with 2 columns of 4 buttons. Locate the GPS button
5. Press and hold for 5 seconds. It will beep one and then turn green
6. Press the BACK button in upper right hand corner
7. Now you can use all the NAV functions while in motion. When you turn the car off the NAV will reset to normal and you will have to do this procedure again when you restart the car.

Hey there,

do you (or anyone else) know of a way to get the trouble codes for the RX 300's without navs? I used to be able to get the codes on my Dodge Dakota using a sequence of on-off switching of the ignition/key switch. I'm betting that there is a way to do it or the RX's its just I've yet to discover it. Thanks!

OBD-II code reader. The dealer will do it. Many autoparts stores do it for free.

i found the menu (thanks), but what does each diagnostic test do? im still afraid to touch anything in there.

Like I said, I wouldn't touch anything that has "Memory" in it. The rest are fine. I messed with everything else with no problems. When I get back form vacation I'll take and post some pics that expalin it better. In the mean time, play with it but just don't hit anything with "Memory" in it.

Guys,

I need some help:

I have tried all of the above, and I can get into the "secret menu" with no problem, BUT when I try to do the GPS override, I get nowhere. When I have pressed the upper left corner ... etc., and press the lower right corner, I get the coverage map of the various European countries. If I try the other way, nothing happens at all.

I don't know if this matters, but I have the RX300, 2004, w. ML sound system and navigation. The version is 2004-2005, ver. 2, for the European market.

TIA

I've only tested this on US market vehicles. Try Lexus Owners Club Europe. http://euro.lexusownersclub.com/forums/

Definately some groovy stuff in these menues, now if someone could just document what it all is?

BTW - Here is another (more easy) way of getting into the menues:

• Hold the info button in, and whilst doing so turn the lights from off to on (not auto) and back to off 4 times until a menu appears.
• Do it again from the same menu and another set of options appear.

To get out, press the Display button for a few seconds.

lol what is with all of these secret menus...

A great thing about that secret menu with all the diagnostic stuff is that you can turn on the backup camera while your driving, makes you kind of dizzy but its always fun to see on the freeway

Can anyone post a picture of the label of the generation 2 and 3, version 5.1 Nav update?

hi, i need some help. i went in the secret menu, and press the eng_tab. now i have my nav say "insert correct disc". do u have any way to fix this problem? plz let me know
thanks

Im just guessing here, but maybe you changed the default language and its looking for another country's DVD. perhaps try doing it again until it comes back to accept the CD you own

Mike

Take it to the dealer and get them to repair it under warranty. Tell them it just started acting up. Other than that I'd say you are going to have to reset the nav. Read this post, easily found with search feature, Navigation Error: Incorrect Program Disk

Added pictures to the first post showing how to get to diagnostics screens.

Have you had luck turning the backup camera ON while you driving? If so, how to do that? Thanks!!

yeah...get into that diagnostic menu...and then click on check camera or something while the engine is on

Yep. As RX330driver said, but the only thing I don't like is no radio while in DIAG mode. I don't see much use for it though since you have a rear view mirror.

So can you view the camera while driving on the highway?

lol yes...but its dizzy-ing

How do you turn the camera on/off while driving?

lol and were back to the beginning. Read this post and get to the DIAG menu, and then there is a button for camera check, tis that simple

Anybody have the sequence for my new RX-350? It has nav DVD ver.06.1. Thanks.

hei anyone know how to turn off the selt belt beep beep sound's in rx350? appericate if anyone can help.

I did a cut and paste from another string. This worked for me, I have the 2006 IS250AWD.

Good Luck!

Here is an example to turn off the seat belt warning:

1. turn the key to the ON position (press Start 2 times), foot off the brake
2. cycle the odometer with the trip reset button until the ODO is displayed (not trip A or B )
3. turn the ignition to the LOCK (OFF) position
4. unbuckle the driver's seatbelt if it was buckled.
5. turn the key to the ON position (Press Start 2 times). when the dash lights have come on, press and hold the trip reset button and count a slow 12 seconds. (editor's note, hold it more like 30 sec)
6. while still holding the trip reset button, buckle the driver's side seatbelt.
7. the odometer display should read "b ON" or "b OFF". toggle the beep OFF with the trip reset.
8. the process should be completed when you unbuckle or turn the key off

I have a 2007 GX470 and the Nav hack does not work. Is there an updated hack that works?
Thanks.

Way cool find! I gather those of us on gen 2 and 3 (an '02 RX300) are SOL.

I got my 330 nav system locked out after an oil change, dunno what happened but it wants a different disc LoL. I'm gonna haul it back to the dealer and make them fix it.

But my contribution to the hacks thread would be this:

On "Need Different Disc" screen:
Tap top right, bottom right, then top right again. Car makes a "Cha-thunk" noise from the back. Not determined what yet, pretty sure not the DVD reader cause it comes from other side of cargo area.

Also on "Need Different Disc" screen:
Tap top left, middle center left, and left bottom. Screen turns off and turns back on. Not sure for what purpose.

Hi all,
I have a 1999 Harrier/RX300 with a cd nav unit, are there any hacks for the first gen units?

Thanks

Hey guys,

A question from Oz about the diagnostic menu - does anyone know about the Bluetooth Voice Quality setting page does?

Specifically, the "Voice Quality Type" number? I assume (dangerous I know) that the Receive Voice/Send voice levels are simply volume adjustments, but it's the voice quality that I'm curious about.

The voice quality on mine is, well, pretty ordinary at the best of times.

Cheers, Dave

Great post!

OK, I have a non-NAV '04 RX330. If I leave the climate control at LO temp setting, the recirc always turns on when I start the car. Very annoying, especially on days when I don't need to run A/C and don't realize what happened until the air inside starts getting very stuffy.

I'm sure that there's a hack to turn this feature off. Any help?

I don't see this topic here, so I'll post and hope someone has answers or ideas.

I foolishly upgraded my 2005 RX330 (Gen 2) nav DVD at my local dealer for the bargain price of $265 + labor for a grand total of $327.50 before checking these Forums. I was unhappy afterwards because nav was non-functional since they hadn't completely closed the DVD compartment door. After returning to dealer to get this done & regain functionality, I became more dissatisfied when discovering the override functionality gone.

Is the override really gone in the 07 Nav Disc Update G which I received? Is there really no override/hack other than the hybrid DVDs mentioned in another thread (I'm sure I don't have the previous DVD that my car was loaded with at delivery in late 2005)? Does anyone know of an after-market solution for this; I would happily buy one after-market.

I've already registered at www.lexusoverride.com. My next thought is to return to the dealer and pay them $327.50 to reinstall the previous nav DVD.

Thanks for thoughts on this.

I tired this. Went into Diagnostic Menu but the Check Camera is disabled. Dont know why, but tried a lot of things touching various parts of screen, applying light to high pressure but no response.

Guess in the 2008 version they disabled it!

has anyone tried this? specifically with a '05 RX-330?

We just bought our first Lexus yesterday
2002 rx300 2wd, 69k, very clean, leather, sunroof, heated seats,nav "sort of"
The nav doesn't work yet.
We picked the car up Friday, drove it over the weekend and purchased it Monday Nov the 10th
The nav system display showed no disc from day 1.
The dealer said they checked it and there was no disc present when the original owner left the vehicle on the lot. So I did a little research and found out what the most current software version of the disc would be.
Then I had the dealer order one monday.
Today I got a message saying that the new oem lexus gen 2-3 compatible ver 8.1 map disc had arrived. My wife took the car over there on her lunch break the guy at the lot told her that it would not go in so he pushed the eject button and out comes the original disc. I think possibly he did not have the key turned on when he originally tried to eject the disc so he thought there was nothing in there. The guy is a friend so I cant really be mad about a simple mistake I could have made my self. According to my wife the system will not recognize either disc. WTF?

I don't know what version was originally inside the unit as my wife was in a hurry to get back to work and could not be bothered over the phone, but I'm getting the feeling from what I've been reading today that if it was a much older version that I cannot directly upgrade to v8.1. even if there are some tricks I can try to get the system to recognize either disc.

Any help would be greatly appreciated.

Sounds like your nav system is screwed up, if it couldn't read the disc that was present in the drive. Get the dealer to troubleshoot it. They will most likely opt to replace it.

Hey rod, any solution yet? I'm in the Jackson, MS area here. Are you using Herrin-Gear?

Ray
