Have a 2006 RX330 with original navigation system (ver 4) I just replaced the map disk with a new 2009 edition,bought new from Sewell in Dallas. Installed it myself, seems to work just fine except the navigation override procedure that use to work does not.
The procedure I used was: Menu, Volume, upper left corner, left corner, upper left corner ,lower left corner, and then hold the override button 5-10 seconds on the screen that appears.
Have I lost the override option by installing the new 2009 map disc or is there an override for this combination as well !!!!!!!
