Where did you find that tsb? I checked the NHTSA site and couldn't find it?

Does anyone have an issue with the person on the receiving end of calls getting static, humming sound and volume in/out? Vehicle is RX 400h 2007, Nav/ML package. Phone is T-Mobile Motorola RAZR V3. I have no issues with the sound quality for the incoming call. I've accessed the sub Menu (HOLD INFO BUTTON & PARKING LIGHTS ON/OFF 5 TIMES) and adjusted the receiving/sending sound level and the quality type? Does anyone have any literature on this sub-menu? What values default values should be here? Mine are all blank? Took vehicle back to dealer, they blamed it on phone. Updated software for phone and no improvement:( IS IT THE PHONE OR LEXUS BLUETOOTH?
