COZ Posted May 11, 2006 Posted May 11, 2006 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) - Press DISPLAY button - 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) - The Service Menu should appear. The only thing I wouldn’t mess with is the Memory Copy and paste stuff. - 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. 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.
COZ Posted May 11, 2006 Author Posted May 11, 2006 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.

tmastres Posted May 11, 2006 Posted May 11, 2006 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!
COZ Posted May 11, 2006 Author Posted May 11, 2006 OBD-II code reader. The dealer will do it. Many autoparts stores do it for free.
Rx330driver Posted May 12, 2006 Posted May 12, 2006 i found the menu (thanks), but what does each diagnostic test do? im still afraid to touch anything in there.
COZ Posted May 12, 2006 Author Posted May 12, 2006 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.
KillerBob Posted May 20, 2006 Posted May 20, 2006 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
COZ Posted May 21, 2006 Author Posted May 21, 2006 I've only tested this on US market vehicles. Try Lexus Owners Club Europe. http://euro.lexusownersclub.com/forums/
KillerBob Posted May 21, 2006 Posted May 21, 2006 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. KB
Rx330driver Posted May 21, 2006 Posted May 21, 2006 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
COZ Posted June 24, 2006 Author Posted June 24, 2006 Can anyone post a picture of the label of the generation 2 and 3, version 5.1 Nav update?

Rhody401 Posted July 6, 2006 Posted July 6, 2006 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
COZ Posted July 8, 2006 Author Posted July 8, 2006 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
COZ Posted August 27, 2006 Author Posted August 27, 2006 Added pictures to the first post showing how to get to diagnostics screens.
Kutten Posted August 28, 2006 Posted August 28, 2006 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 Have you had luck turning the backup camera ON while you driving? If so, how to do that? Thanks!!
Rx330driver Posted August 28, 2006 Posted August 28, 2006 yeah...get into that diagnostic menu...and then click on check camera or something while the engine is on
COZ Posted August 29, 2006 Author Posted August 29, 2006 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.
Kutten Posted August 29, 2006 Posted August 29, 2006 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?
Kutten Posted August 30, 2006 Posted August 30, 2006 How do you turn the camera on/off while driving?
Rx330driver Posted August 31, 2006 Posted August 31, 2006 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
Mike K Posted September 10, 2006 Posted September 10, 2006 Anybody have the sequence for my new RX-350? It has nav DVD ver.06.1. Thanks.
