I understand the issue about the Nav feed to the GPS, and installing a switch to defeat the speed sensor is exactly what I am looking to do. Any suggestions about how to go about it? Thanks.

Does anyone know exactly how to disable the speed sensor that feeds into the Nav system on the 2004 Ls430? I understand that if it is disconnected I will be able to enter a phone number on the touch pad of the handsfree telephone pad while the car is driving. This is much safer than fumbling with my cell phone while driving, but Lexus decided that it was in its best interests not to let you use the car's features to do that. They would rather force you to dial on your cell phone, which is more dangerous. That's what happens when you include a lawyer in your design team I guess.

PLease be advised that not all Sony Ericsson bluetooth phones will work with the 2004 LS430 hands-free system. I had a T610 that worked with the car, but when I upgraded my phone to the new P900, I found that the P900 did not sync with the car. Sony Ericsson's tech support said that the P900 and P800 support only headset mode, and the LS operates in hands-free mode. Hence the latest phones from SE will not work, and you will have to stick with the older models.
