I was messing around with the nav system on my 2004 Gx470 and mistakengly changed the language option and now the screen is in Japanese and Says CAUTION in english it also says that the DVD is incorrect. Does anyone know how I can fix this problem and get back into the configuration menu?

 

If you can't find out how to get back, there's a Nav/Bluetooth expert at Magnussen Lexus in Fremont, CA (510-657-6600). Can't remember his name.

 

either u need to get the NEW ECU or get the Disc from Asian....depend on the ys u have, if ur GX is after 05 just call the dealer for rescure disc..they might charge u a little labor insted $5000 for New ECU

 

U need the NEW ECU
