FM Transmitter car charger issue
 

I have been looking around trying to find out more info about the issue of fm transmitter appearing not to work when I have car charger plugged in and i'm a bit confused having read what seems to be contradictory information...

Bug 6792 seems to suggets it is a bug, and although not fixed in 2.2009.51-1 update should be at some point in the future...

Various posts I have read on here seems to suggest that the strength of the fm signal drops when either PC usb or car charger USB is plugged in thus causing the charger issue in the car...

So, here's what i've found:

1/ FM trans won't work when plugged in via USB on PC and I get a little yellow message telling me so..

2/ FM trans will work when plugged into mains via Nokia USB charger

3/ FM trans won't work when plugged into car via genuine nokia charger (can't recall model number)

I've installed FMBoost and it doesn't affect 3/ above.

So, my question is, is the FM transmitter car charger thing a bug? Does the latest firmware released on 16th Feb (which I still can't see!) fix it? If not is it likely to be fixed in a new update at some point or is it something which will never work....

Might need to flash phone. I have a micro usb charger from Sprint that I use in my 2004 Chevy Malibu. the car charger plugs into car and phone. the reeception drops when I first plug in the car charger but after I restart the program it come in a lot better. i also downloaded fm boost. you must use that after you plug in for better sound in car. I personally have not had the issues you describe with my fm transmitter. the fm boost app is in the app manager. no extras-devel or anything. hope it helps

fm transmiter interfaring with the usb charging, it will produce lose in quality of the audio to your radio. The reason may be the FM transmiter is using the USB port as antenna. So charging will make the FM transmiter either stop working or lose in sound quality. Solution for now is to not use FM transmiter while charging.

anyone report this bug yet?

Re: FM Transmitter car charger issue
 

actually, I'm confused about how to use fm boost.
Is it activated after installaton?
or do I need to run it from the menu?
looks like it starts the xterminal and run some script and exit
should I run it before turning on transmitter?
or run it after turning on the transmitter?
do I need to run it everytime after turning on the transmitter?

that app didn't do anything at all on mine. just execute and then exit and there is no changes to the fm

Thanks for replies but am no nearer to understanding whether this is a bug or not! Any nokia people or N900 gurus care to comment?

Re: FM Transmitter car charger issue
 

FMBoost does two things. First it turns on the fm transmitter - second it changes a value in a specific system file that increases the "power level" of the transmission, resulting in better reception.

It could be an FCC(and/or EU equivalent) rule to disable or reduce the power of such transmitters. Because the charger lead will act as an antenna. They only want the signal to go a few feet not a few hundred feet.

Re: FM Transmitter car charger issue
 

fm boost needs to be run after switching on fm transmitter and after plugging in charger.

Plugging in charger, removing charger, or switching fm transmitter on/off will nullify fm boost's changes.
