I drive a 2004 RX 330 and the only thing I cannot do while driving (without first performing the override sequence) is enter a new address. All other controls seem to work for me (although I don't have the blue tooth dialing option).
Now, for anyone else who, like me, can't use the oft repeated "Menu -> Volume -> UL, LR etc.." sequence to override the new destination blocking feature, here is a link at www.cartv.com as well as three sets of instructions for performing the override on various Lexus/Toyota incarnations. I'm relatively sure these will not help with 2006 or later models but it sure helped me and I wanted to pass it on to others who may need it:
(This is the one everyone repeats in this forum)
Step 1 Press The Menu button
Step 2 Press the Volume button
Step 3 Press The Upper Left of the screen
Step 4 Press The Lower Left of the screen
Step 5 Press Upper Left of the screen again
Step 6 Press Lower Left of the screen again
Step 7 Press and hold the Override Button until system beeps
Step 8 Press Back Button in upper right corner
Done! The Buttons For Navigation & Phone are now accessible
(I don't have a system button so I couldn't use this one)
Older Lexus and Toyota Systems may require a slightly different process:
Step 1 Press The Menu button
Step 2 Press the System button
Step 3 Press The Upper Left of the screen
Step 4 Press The Lower Left of the screen
Step 5 Press Upper Left of the screen again
Step 6 Press Lower Left of the screen again
Step 7 Press The Lower Right of the screen
Step 8 Press and hold the Override Button until system beeps
Step 9 Press Back Button in upper right corner
Done! The Buttons For Navigation & Phone are now accessible
Some versions may use the following steps:
(Worked for me! )
Step 1 Press The Menu button
Step 2 Press the DVD button
Step 3 Press The Upper Left of the screen
Step 4 Press The Lower Left of the screen
Step 5 Press Upper Left of the screen again
Step 6 Press Lower Left of the screen again
Step 7 Press The Lower Right of the screen
Step 8 Press and hold the Override Button until system beeps
Step 9 Press Back Button in upper right corner
Done! The Buttons For Navigation & Phone are now accessible
