Just purchased a new 2005 RX 330 with navigation. love the vehicle, but disapointed with the Navigation system with blue tooth, as can not use the system while vehicle in motion. does anyone know how to disable the motion sensor, so that the navigation and phone system can be fully utilized while in motion. I understand that it is not too difficult to do on a 2004 system, but with the changes for 2005, that alteration no longer works. Would appreciate input as this is a real problem for a person who is in the auto for many hours of the day.
