I have done some research on it and couldn't find one. Here are some threads. http://www.clublexus.com/forums/gx-first-generation/532940-trailer-hitch-install-with-photos.html http://www.clublexus.com/forums/gx-first-generation/474702-anyone-have-the-integral-hitch.html I ended up getting an off-shelf one. Modified and mounted it on that plate. I use for bike rack only. http://www.walmart.com/ip/Reese-Towpower-Step-Bumper-Receiver/15125807

I got the same thing by messing around the serivce menu. Wondering is there any solution out there? :cries: I haven't found anything yet. I still waiting for a nice day to pull out my passenger seat, then the nav drive, then the CMOS battery in hopes it will default back to a useful state. I will certainly post if i find anything helpful. Last night, I pulled the Nav ECU out from underneath the passenger seat. Opened the ECU and disconnected the SRAM backup battery (did it a couple times). I had no luck! Still showing the same screen. Wondering how other people in the club were able to do it by this way. I found a threah of one guy had similar issue and could only get it fixed by loading a newer version DVD. Really need help from whoever fixed the problem. UPDATE: I FIXED IT !!! Tonight, I followed the steps that RXCHICAGO posted in this thread (thank RXCHICAGO for sharing!) http://us.lexusownersclub.com/forums/index.php?showtopic=29621&st=30 and finally fixed the problem and updated to v7.1 as a bonus.

The navigation DVD player is under the front passenger seat. Pop the cover off and press the eject button, you can get the DVD out and replace with an updated one ($199 from dealer).

You can get it from here, http://www.lexuspartsnow.com/Page_Product/PartDetail.aspx?model=GX470&year=2006&catalogCode=781450&VAID=4404&selectConditions=()&goBack=false&sectionID=4&isBigPicture=False&componentsID=86-02&componentsIndex=30, though it is not cheap. Or go to a car stereo to replace with aftermarket one.
