I just got my 06 Coupe with Nav and Premium. I have been using the Bluetooth phone system with my Treo 650 a lot, so far I like it. I have two gripes and I'm wondering if there is any solution for them. One, can you adjust the microphone volume of the car in any way? I wasn't able to find anything about it in the manual, but I feel like there would be a way to do this. Second, is there any way of displaying who is calling? I doubt there is, but if there were something that could display a Caller ID on the NAV system that would be amazing. Overall, I'd say the phone system is good but the system on the Lexus IS350 (probably other models also) was much better when I test drove because it was so nicely intergrated into the NAV.

 

use the volume up/done after you push the button to activate bluetooth. this will control the audio for the phone mode. it remembers it too, which is nice. no luck with displaying the phone # tho :-/

 

That will only adjust the speaker volume for the phone, as far as I know there is no way to adjust the microphone volume. But yea no dice on the display, I have specific ringtones assigned to people who call me most frequently that way I dont have to look at the phone to see the caller ID.

 

I've been trying to figure this out myself.

:Bump:

 

Here is another question: My left speaker does not work w/ bluetooth. It works great with music, but whenever I use the phone, the left front speaker is bypassed. Is this normal? Thaks, Jason

 

If you have a coupe the bluetooth only uses the front passenger speaker. It's probably to prevent feedback.
