I am considering getting a 2004 LS 430, and have a question about the Bluetooth cell phone usage .... The reviews talk about the fact that dialing is immobilized when the car is in motion, except for speed dials. However, when the car is in motion, can I still dial by voice recognition, by speaking a voice command and a desired new phone number? If not, seems very limiting. Your input would be appreciated .... Thanks Kive
