Nokia 6120 car kit causing radio interference

stupid force cradle is only a "coupler" and probably a badly tuned one at that - simply its picking up the radiated signal from the phone and causing that to be transferred to the radio via wiring etc.

move the antenna wire running to the cradle - or get better coax for the antenna - many cheap antennas have crappy coax - not sure what antenna you have. also where is antenna on car in relation to FM radio antenna??

It is purely and simply Telstra's fault just ask Daveo.

ROTFLMAO

Cheers Steve.

Dalb,

This is an unusual interference symptom I have not seen before.

There is/was an issue with the 6120 causing echo at the remote end when using a car kit, but that has been resolved with a firmware upgrade now available.

If you haven't done so already, I would suggest downloading the "phone updater" application from the Nokia site and upgrading to the latest release.

Bluetooth should not cause any interference to FM radio.
Maybe search the Nokia forum for any similar incidents, particularly with the 15W car kit.

I use the CK-7W car kit, which also uses bluetooth to interface with the 6120 and I also have the Force Technology cradle.
As the force cradle does not physically connect to the car kit I don't think this is the cause of your problem.

Another thing you can try is to unplug the cradle's power plug from the ciggy socket and see if you still get the same effect, or disconnect the external antenna connection, if you have one.

It is a process of elimination sometimes.
Failing all the above I'd go back to the installer and demand further investigation. Maybe it's peculiar to the 15W car kit.

I've noticed that some Nokia phone car chargers cause interference with radio, does the cradle also charge the phone?

that may be it - the crappy force cradles need a seperate power supply - usually provided by $2 ciggy light lead adaptor thingy.

If you have that type - unplug the ciggy lead and see if it goes away

Those leads have nasty switchmode power supplys in them - lots of EMI!

We use the Force cradels and have not got a problem, it maybe to do with the passive antenna coupling being close to the radio.

1) If you have the phone in the cradle with bluetooth turn off does it still do it.

2) Does it only do it when you are talking on the phone.

3) If you disconnect the power from the cradle with the phone still in the cradle does it stop the interferance.

4) If you have the phone causing interferance in the car kit does it still happen when the phone is behind or near the car cradle or radio.

The power source is through the car kit.

It's good to see people blaiming Force for the problem, Force only makes the cradle the rest is Nokia.

When the phone is in the cradle and causing interferance grab some tin foil and a lenght of wire, rap the foil around the back of the cradle. Connect the wire to the car body earth point and with the other end of the wire touch it on the tin foil...does the noise go away.

Regards Richard

Opps sorry we have the Nokia CW7 car kits, they come with a charge cable that plugs into the bottom of the Force cradle and then into the Nokia Bluetooth car kit.

I have just ordered a Force cradle for my Nokia 6120.

What is the best antenna to use with this?

Thanks.
