bluetooth / hands-free issues - GreenHybrid

I have a TCH and Moto v710 and when I talk to anyone who is on hands-free (earpiece or car), I get horrible intermittent issues. Audio will cut out for a second or two for either my speaker or my mic (as heard by the other side). I will also get intermittent issues with very loud noise, again sometimes on "my" speaker side and sometimes on the other.

Has anyone else had similar issues?

I have the v710m and have not had any problems. I have only heard people say it sounds like I am far away but I have since then increased the BT mic volume. My girlfriend who has the Razar, in my opinion, sounds much worse (although she drive a RAV4 and not a TCH). Try leaving your self a voice mail.

Also, does this happen even when the phone is right there with you in the front of the car? Does it happen all over or just in certain places (geographically)?

On a side, I have sometimes had connection issues where it would fail to connect but then shortly after try again and work just file. I am speaking about the BT connection.

It happens everywhere geographically. I can be on a call via HF and it's bad, switch to the handset and the call is crystal clear. I have zero call quality issues with the 710 itself.

I have tried separating my key fob and the phone by as much as is possible within the TCH cabin. Where the phone is doesn't seem to have much effect either. The status of the HVAC seems to be irrelevant as well.

I need to take the time to borrow the wife's non Moto BT phone and pair it to my car, and also try my phone in her Prius.

On a related note, how does one change the BT mic volume on a NON-NAV TCH?

Well you can rule out interference. I would do as you said you will, try another phone and try the phone in the Prius.

To up the volume....

Setting Bluetooth sound level on 2007 Camry Hybrid w/ Navigation

In my '07 Camry Hybrid w/ Nav, my Motorola V3 Razr paired fine, and I could hear people fine when using handsfree, but people I called were always asking me to speak up. I couldn’t find a microphone sensitivity control in the user menus. I called Toyota service and they told me how to bring up the diagnostic screen (a function reserved for the service technicians). There I was able to adjust the Bluetooth "send voice level". Following are the instructions:

-Turn on car power (doesn’t need to be started)
-Press Map button (hit I Agree first if needed)
-Press Silver “Disp” button (bottom right side of display – physical buttong)

-A kind of divided screen appears with “Display” on top and contrast/brightness on bottom. While this screen is displayed, do the following very fast:

-Alternately touch the screen under the Display line, then above the Contrast line. Keep doing that over and over until the diagnostic screen appears. If it doesn’t work, keep trying. It took me a few tries. Touch the top, then the bottom, then the top then the bottom, all very quickly. Using two fingers might be too quick, as that didn’t work for me. I used my pointer finger. There is no icon, you just have to stay under the top line and above the bottom line.

The System Check Mode screen appears
-Touch Menu in upper right
-Touch Bluetooth Tel Check
-Touch Hands Free Volume Quality Set
-Change the “Send Voice Level to a higher number (press the up arrow next to it).
-Get back to the main menu
-Turn the car power off (there’s no other way that I see to get out of the Diagnostic screen).

The “Send Voice Level” on my ’07 Camry was set at zero. I changed it to 3 (5 is max). I then called my voicemail using handsfree, left a test message, played it back, and my voice was much louder. I haven’t tested it on the road yet.
