Guest Mountaindog Posted May 3, 2006 Share Posted May 3, 2006 I just screwed up my navigation by accidentally hitting load "US-TAB" under LOAD section, of the "secret" menu... Now the navigation system appears to be inoperative and reads on the opening screen a message in English, but mostly Japanese. It reads(the English part), "Error; System unable to access the program" "Incorrect Program Disk, Please insert proper disk". Anyone know how to reset it ? Please help.

Contact your local Lexus dealership and request them to have their local FTS send them the repair disc to reset your navigation ECU. I would highly suggest that you not adjust anything in this hidden menu. Quote Link to comment Share on other sites More sharing options...
jainla Posted June 16, 2006 Share Posted June 16, 2006 You can also try disconnecting the battery for a few moments. You might lose your radio presets but it will reset the navigation system.
