    I'll add car speakers, as well since I was using my V3 merely for data use and the car speakers buzzed.

    (No, I wasn't playing around with my data plan while I was driving.)

    My Sony Ericsson z520i did this all the time, while my Samsung s307 doesnt do this at all. Has to be a problem with the hardware. They are both 850/1900

Yes, I get the buzzing sound on my Altec Lansings, and if I make/receive a call the buzzing gets so annoying that I end up turning off the speakers for the duration of the call.
    I agree with this. I lived for a year and a half in a 850-only roaming area (Dobson) and placing/receiving/being on a call would make it unbearable to be in the same room with my tv. I have sinced moved and rarely (if ever) get interference.

    I like 850's building penetration, but it makes me wonder what the signal is doing to my head!

    But again, the phone that did this was a SE t637, so maybe SE's do this more than others...

    Most speakers are shielded as are computers and other electronic equipment. They just aren't shielded adequately for a signal source as strong as the cell phone. The only remedy is to move the cell phone away from the computer and speakers. The "random" noise you hear is the cell phone "talking" to the cell network. It's called a handshake and it's how the cell phone system aquires your cell phone.

    Peace....

    Have the same thing with TV, Computer and car stereo. I know what causes it and adjust accordingly. Doesn't phase me any more. And I am new to GSM.

    HMMMMMM........Im about to tear my hair out of my head with the amount of noise that comes through my car speakers when my cell phone is communicating with the towers. I guess the only solution is to pull my car speakers out and try to better shield them. Im gonna go to an auto shop and see if they have experience with this stuff.
    I just migrated from TDMA to GSM and my V60 TDMA phone only buzzed the speakers when I was receiving a call (Kinda cool actually), but now it buzzes much louder and often when not receiving a call....I have a Nokia 6102 BTW(sweet phone!).

    ......GSM kicks @ss!!!!!!!!!!!!!

    The problem isn't with the car stereo speakers. The phone is not close enough to them to case RF interference. Try simply moving the phone away from your car stereo head unit. Sounds like the phone is mounted on your dashboard next to the head unit. If I'm wrong, my apologies. My experience is that RF interference from the cellphone will cause noise on wire-line telephones, computers and stereos. My father was a HAM radio operator for years and his signal used to mess with the next door neighbors' TV.

    Moving the phone to the back seat helps the problem, but what good is that?
    I notice that when the problem occurs, if I cover the phone with my hand, the noise gets a little lower and muffled.
    Im gonna ask around and see if my friend who's an auto-electrical guy knows of a known fix and then Ill post it on here if it helps.

    All he has to do is get a headset with a longer cord.

    BT is even better, toss the phone in the backseat.

    Does anyone Know any more about the "handshake"? The frequent uninhibited transmission while at rest?

    It's just a re-registration to tell the network you haven't gone into a "no service" area or had your battery die.

    It happens updates every 30 min or soo, i guess, if not using data, (automatic mailbox update, signed into a chat service) Because it pulsates my CRT moniter, and i can tell by how many shakes in the screen if im goign to receive a call or get a text message.
