(I actaully mean the "Tele-Aid" system. Sorry if I incorrectly described it as the phone).
Does anyone out there know how to either disable the now usless Tele-Aid system, or at least lower the speaker volume.
As it is no longer supported, due to the conversion to all digital cell service, it would be nice to eliminate the initialization noise on start up. Sounds like a dial tone for a second or two.
Thanks,

Reason: May have been incorrect in my description
Do you have a telephone 'base' in the front console storage bin (above the ashtray) and a handset? There were several different phones available.
If so you can get a pair of 'radio keys' and pull the radio. No need to disconnect it. Just slide it out far enough to get your hand in the opening and feel for a plastic latch in the center at the top of the telephone compartment. Release it and slide the telephone module out of the dash. Disconnect the cable and that should do it.
There is a storage bin replacement part called a 'cubby' which replaces the phone and gives you some storage instead of a 'hole' in the dash but they can be a little hard to find.
Thanks, but no. The phone is missing but it was listed on the build sheet.
I am the third owner.
There seems to be a connector for it in the center storage area (top armrest compartment). I believe the start-up initialization noise is from the Tele-Aid (ONSTAR) system, of which I am trying to lover the volume.
If you press the info or SOS button you get a VERY loud "Unable To Place The Call" message that repeats for about two minutes.
That is the volume I would like to reduce.
Thanks again,
Ron Y
Sorry I wasn't of much help. There are certain parameters that can be adjusted using the STAR computer at a dealership. You might call and ask if that can be adjusted by them. Good luck.

I don't hear any initialization noise at start up. I have never paid for TeleAid but the last time I pressed the SOS button (last year sometime) a woman answered the call. I'll have to try that again to see what happens.

I believe MB has a bulletin for the dealers on how to disble Tel-Aid. If you pull the fuse, you will get an "error" code in your instrument panel. I would immagine removing the connector would do the same. I have Tel Aid but never resubscribed, and pushed the info button once by mistake, it is almost impossible to cancell the call unless you turn off the car as I remember. I dont get the beep, but did not install the telephone since it was not T-Mobile, and gave the handset away.
There is a storage bin replacement part called a 'cubby' which replaces the phone and gives you some storage instead of a 'hole' in the dash but they can be a little hard to find.
I have been looking for one of these cubbys for quite some time. Does anyone have any leads as to where to find them?
I got the same problem on my 2000 C280. I just called my local MB dealer (Barrier in Bellevue) and they told me that it is the teleaid that is producing the loud noise. They can remove the analog teleaid system, but it would run my anywhere from $280 to $420. He also said that Mercedes is advising people not to remove the analog system as it could harm other components in the car (e.g. your radio)
I am definitely not spending $300 on getting that thing removed. If there is anybody that has stopped the teleaid noise, please help us out here.
