dsgibsonMN61 Posted October 27, 2007 Share Posted October 27, 2007 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? Quote Link to comment Share on other sites More sharing options...
gordonw Posted October 27, 2007 Share Posted October 27, 2007 It could be the microphone in your vehicle. There is a tsb for the microphone due to noise during handsfree calling. Its essentially a new microphone. Have your dealer check tsb EL007-07. It applies to the 2007 RX350/400h. Quote Link to comment Share on other sites More sharing options...

gordonw Posted October 27, 2007 Share Posted October 27, 2007 Probably because its not safety or recall related. Its just an update that mentions there's a new microphone part. Quote Link to comment Share on other sites More sharing options...
