I found this info from caranddriver.com. This cost $$$ but it seems to work. NAV-SYSTEM UNBLOCKER: We have complained ad nauseam about the so-called lawyer’s screen that comes on after startup on many navigation-equipped cars. Coastal Electronic Technologies circumvents this with the $229 Ultimate Lockpick (www.coastaletech.com; 800-507-2234). After removing half the interior of the RX to access the back of the navigation unit, we plugged an Ultimate Lockpick 1 into the correct slots and then bypassed the “I agree” startup screen. The Lockpick allows full use of the navigation system while driving and unlocks the direct-dialing keypad for use with a Bluetooth phone. Still better, it converts the nav screen into a video monitor, for which you need a video source, such as an iPod or DVD player, which is then plugged into a connection in the glove box before pressing a couple of buttons. Lockpicks are available for most Toyota and Lexus vehicles and for GM’s new full-size sport-utes. To allow all navigation and Bluetooth functions to be used while in motion, simply press the destination button and then press the bull’s-eye in the upper left corner. A series of automated screen changes later, and the touch-screen buttons that used to gray-out while driving retain their functionality. We don’t recommend driving with your head buried in the navigation screen, but we really like this product because if we had a passenger, he could enter a destination on the fly. — K.C. Colwell
