I have an '06 GS300 and when I got it back in December of '05, I thought the phone feature was going to be great. Didn't take long to figure out that I was better off just using my phone with a bluetooth over-the-ear device. Using the LCD panel in the car, you can't use call waiting, can't dial using the dial pad on the LCD (grays out when you start rolling) or download a phone book very easily. I had an '08 ES350 for a loan car when my GS was in for service and the voice dialing does help but is still cumbersome. You would think Lexus, in their "relentless pursuit of perfection", would figure out the phone feature just isn't up to par. This feature is about as useful as the parking assist system in the '08 LS460's. My 2 cents worth.
