On my 2005 GX, the Bluetooth microphone makes voices sound weak and far away. This makes it difficult for the speaker to be understood. My Corvette's hands-free is clear as a bell. Is this problem unique to the older GX's? Is there any kind of fix?

Does anyone else experience this? Could it just be a problem with my car?

it might be ur fone...but there is a service menu u can acess(only meant for dealers to use) there is a bluetooth adjustment menu in it.....if u wan let me know and i can tell u how to access it and u can mess around with it...but becareful there is an option in there that would lock ur whole system if u touch.....
let me know

Balky23, PM sent. Thanks!

Did this work? I have the same problem with my 2007 Lexus.

Could someone post the instructions in this thread? Much appreciated.

i have the same problem

I had the same problem and found these instructions posted on a Lexus IS forum:

"first hold the "info" button (I did it for about 5 secs) then switch your parking light switch from off-to parking lights-repeatedly while still holding the info button....it takes about 5-6 cycles...an poof the NAV screen enter yet another Service menu. From there I navigated to a bluetooth menu where I was able to adjust the Microphone volume higher so that people can hear me better!"

I have a 2006 GX470 and I was able to increase my microphone volume this way. I believe it is called "send voice volume" in the menu. I set it to 3 and people no longer keep saying "I can barely hear you"

Of course, this is a service menu menu so be carefull what you change.
