(my apologies in advance for also posting this in the Lexus Electronics section)

If I update my Generation 4 navigation DVD to the latest version, will I lose the ability to select destinations while the vehicle is moving?

Currently, I use the hidden screen method to enable the nav features while the vehicle is moving (via the Volume button, top-left corner, bottom-left corner, etc. procedure). I'm afraid that if I update the DVD to the latest maps, I may lose this capability on which I've come to rely.

Can anyone confirm or deny this?

(my vehicle is a 2005 RX330, using the original DVD).

you will lose this ability

The reason I asked is because while my car was at the dealer for routine maintenance, I asked the service rep about this, she told me that since it is just updating the maps/data (not the program/application), this ability wouldn't be affected.

it's essentially a firmware update, new maps included on the software side

Yes you will lose the override function. I've done it. You can always put the old disc back and and get the override back - it's not permanent when you do the update.
