Phone microphone
Does anyone know if the volume of the phone microphone can be turned up so that the person I've called can hear me better. I just converted from console phone system to bluetooth and since then, I hear complaints that they can't hear me. I also get dropped calls or incompleted calls where before I made the change , this too was not a problem at all. I place a call, it shows on the display that the call is being connected, and then about 10 seconds later....NOTHING..... and it cancels the attempted call. I really hate that I made this change. Most of the time, the onboard system immediately boots up when I get into the car but on a few occasions it doesn't. Therefore I'm driving around missing calls because all along I was thinking my phone was on , when actually it's off.
I sometimes have to turn off my phone and restart it just to get my car to recognize it. Very aggravating.

Have been using Btooth w/my VZ-based KRZR for past yr or so on various new CLs and have had excellent reception/clarity (and certain stretches of CA fwys/roads amongst mtns/foothills have more difficult cell recep issues than most of Eastern US)....
Perhaps a phone/carrier/Btooth synch issue more than a volume adjustment???

I've seen posts claiming that the first BT pucks may have had an issue with the microphone audio level, changing to a later model has solved the issue. Would probably find posts from the Audio & Telematics.
Of course then there are cellular radio issues, if the link is poor, the audios get muted but this is easy to isolate by testing at good signal strength.

I believe that both of you may have the answer.....getting a new phone may solve the problem. It has been giving me problems lately. I'm due for an upgrade in mid January where I can get a new phone for just a few dollars. I know that my wife's 2008 C class has a transmitting and reception volume adjustment on her telematics and I thought just maybe we did too since the two systems look similar but when I tried to do this, I couldn't get the same result.
Hopefully the phone itself is the problem.

"Is is possible to adjust the fixed volume levels? Audio gain adjustments- to be used when customers complain about the volume level on the non car side being too loud or quiet. These adjustments do not have any effect on the processing of the audio."
"Yes it is possible to adjust the fixed volume levels by using the key sequences below. 0000#1* SEND- reduces the volume out of the car by one step (non car side or landline) 0000#10 SEND- standard volume level 0000#1# SEND- raises the volume out of the car by one step (non car side or landline) 0000#99 SEND- factory reset The settings made / adjusted by that procedure will be peramanently stored in the cradle adaptor for each phone type specifficly. Changes made while e.g a Motorola V3 Razr is connected will adjust for ALL Motorola V3 Razr phones."

I went out to my car, cranked it up, phone was linked (but not in a call), I typed in 0000#1# SEND on the keypad built into the car, the display on the comand screen indicated a connection was made , and then within a couple of seconds, a 5 or 6 note musical tune played inside the car as if to signify that a changed actually occured. Afterwards, it indicated that the connection was over. I did this 3 or 4 times thinking that if this is in fact the way to increase the volume, that I'd raised it up at least 3 or 4 notches. I'll just have to test it tomorrow with my wife calling me.

With the bluetooth phone it is important NOT to have the phone in your pocket. You should have the phone out on the seat or resting in the open i.e. the cup holder. This should help you to be heard much better. Sometimes I leave the phone in my pocket and am told I can not be heard well. When I take the phone from my pocket and leave it out it resolves the problem immediately.
