Most of you know of my problem with this issue from another post, but I feel bad for hijacking someone else's thread and figured I should start another one specifically with my problem. I am at my wits end about this.

Here is the problems I am having and seek help from anyone who has had anything similiar.

1. BT module connects with RNS-e with no problem.
2. BT connects with my Nokia 8800, RAZR and with Proxus's phone (forgot the model).
3. Calls can be recieved, sent etc, with no problem,
4. Caller on the other end hears me fine.
5. I cannot hear the caller well at all, turn up the volume on the RNS-e but it only raises the volume slightly, very slightly not enough to hear the other person well at all.
6. When I do adjust the volume on the RNS-e I see my phone screen shows that volume is being adjusted on the phone and when it reaches max on the screen of the phone its at its highest setting, it is not enough.
7. Tried switching Tel+ and Tel - wires no difference.
8. Completely disconnected the OnStar module and backup battery, no difference.
9. Raised the range of the incoming voice decibels per instructions of another member with very very little difference.

From what I have been told the volume is controlled by the RNS-e and not the BT module so the problem lies elsewhere.
Does the BT module have anything to do with the volume control? That is the only thing we havent swapped, we did (Proxus)try another RNS-e unit and the problem is still there.
Proxus is suggesting taking the car to a sound specialist and having him try to figure out what is going on as he suspects that it is a wiring issue.
Proxus says the guy might amplify the Tel+ and Tel - wires if I understood him correctly and run them to a speaker of my choice whether it be rear or front.
I still have to go and see this audio guy, but I am kind of hesitant as that seems a little bit excessive to get this thing to work correctly.
What do you guys think as I am clearly out of ideas, should we try another BT module, could that possibly be causing this? Any and all help is appreciated. I dont know which version BT module I got and if that makes a difference and maybe Proxus can post which version it is that I do have.

Thanks

I still say the one step you must try is replacing the BT module. It may not control the volume, but the audio definitely passes through the module fromt he phone to the RNS-E, so it can be the problem.

Once you have ruled this out, we can try to engineer a different solution.

The only other "simple" thing it could be is a problem in the wiring. Perhaps one of the TEL NF wires is nearly severed or otherwise in distress. This would be easy to check with a multimeter measuring the resistance of the wires from end to end.

Have you checked you have the Tel+/ Tel- in the right pins in the module, could be out by one position maybe?

Pin 8 - NF +
Pin 9 - NF -

You are talking about the BT Module, correct. If so I will check it before I go and let the audio guy tear into the wiring and starts adding amplifiers.

Just bumping for any more ideas for help, still waiting to try the BT module swap with another unit. :(

hate to resurrect an old thread but its better then starting a new one about the same problem i guess....

so i'm having the same issue. people hear me fine, but i don't hear them all too well... i mean its manageable but could definitely be louder. turning the knob on RNSE does little.

so was there any solution for this short of replacing a BT module?
