The high-pitched buzz comes from specific phones as they make a call through the Lexus hands-free system. I had a Samsung T809 originally and it almost always made that sound first, when I made a call. The iPhone 3G I have now makes that sound in my car's speaker on at least half of the calls I make. Some phones do not make that sound at all. My wife's Motorola PEBL U6, when connected to my RX400h's hands-free system, never makes a sound. The first thing you hear is the phone number ringing. I also had a Sony Ericsson w580i before I got the iPhone. The w580i never made that sound in the Lexus either. It just depends on the particular phone, and the iPhone is one that does make this high-pitched buzz you are hearing.

I used a RAZR bluetooth for years with the same system and never experienced that.

Anybody?
