I have a 2006 LS 430 and a Verizon treo 650. It is compatable but everyone complains that my voice sounds distant and soft. I have turned the volume up on my phone with little success. Is my bluetooth system malfunctioning ? Any suggestions? Araesq

 

Best way to troubleshoot this is by testing under same conditions with a non-treo phone.

 

I don't think this is limited to the Treo, I have the same problem with my Moto V710 and V3. I think it is a problem with the BT or microphone setup in the Lexus.
