Mobile phone/bluetooth interference with electronics?

Viktor,

I used a Nokia bluetooth carkit in my Volvo-V70-I and Volvo-V70-II no
interferences with other devices in my car.
Mute device on the Volvo  radio, so the sound on the radio, I had my GSM in
my pocket, not mounted on the dash,
why mount it on the dash ?

Though I am not really paranoid about electromagnetic radiation but I try to not
expose myself to unnecessarily strong pulsed GSM-phone radiation. I try to keep
the radiation exposition as small as easily achievable. The phone regulates its
emitted signal strength in response to the signal strength of the connected base
it senses. Inside the car in your pocket the sensed field strength is smaller
than near a window. So the phone emits more gsm-related radiation in your pocket
near the body quite shielded by doors etc than when placed on the dashboard
under the windshield. For the same reasons the GPS-sensor of my navigation
system is placed there, too - the satellites´ signal strength inside the car
would be too small.

I am less concerned about bluetooth radiation near me.

Viktor

Your concerns about the effect of cell-phone radiation on humans may or may
not be valid (there are conflicting reports), but I certainly agree with
your desire to limit your exposure, just in case! Also, many places here in
the US have enacted laws requiring drivers to not hold the phone to their
ear while driving, in order to keep the hands free to operate the car.
Regardless of the reason, mounting the cell phone on the dash is probably a
good idea.

As for any effect on the car's electronics, I think most of the circuits
would be adaquately shielded by surrounding metal to protect them from the
relatively low-power signal from a cell phone, even at it's highest output
level.

Here in Austria we also have a law which forbids the use of mobile phones
without a "hands free" device while driving (although also phoning with the
hands free device distracts quite a lot). Up to now I have used a device which
is connected to the phone via a cable adapter and which has a little loudspeaker
for that purpose. But especially the Nokia "snap on" connector on my latest
6610i phone has caused contact problems over problems which could not be solved
easily. So I have bought a bluetooth phone and will buy the
http://www.elta.de/de/artikel.asp?Artikel=7540&x=66&y=48&Artikel1=7540  which has
a bluetooth dongle to communicate with a phone.

It really frightens me when driving beside big trucks and see the drivers hold
their phone with one hand and steering with only the other one. Unfortunately
that is not really seldom.


I had a 745 up to now, no electronics under the dashboard. When the phone is
active one can hear it at least in the radio.

Regards
Viktor
