The FM Transmitter is too weak to be of use in most circumstances. I've got it working 'OK' in a 2002 VW Golf (50 MPG), but the quality is no-where near as good as the CD Player. Was testing it out with radios in the house - when placed directly on top the signal is clear, although the quality is missing a bit. Not sure if the transmitter a generally low spec component or if this is just cheap software.

I've just read through 6 pages of mixed reviews and although the question "can the power be upped through software?" has been asked, it hasn't been answered. Is there any thought here? I'm guessing that in some countries the power is down tuned to comply with local laws, but it would make sense all phones in all countries are the same components?

that must be abit annoying for you cash, having a cd and no aux..

if i was u buy a powerfull plug in transmitter- i cant see the nokia one improving-- and with a speperate one you can hear telephone conversations throuh the radio.

like the 50mpg comment

Tried today morning for 5 minutes in 2000 Ford Fiesta - antenna in roof at the front. n900 was placed in front passenger seat. The radio could not pick up the frequency at all. I tried only for 5 minutes with couple of FM frequencies(90 and 88.1). Both didnt work. Later found that 88.1 is already used by someother station. Would give a more detailed try later today and post.

Look at the directory /sys/class/i2c-adapter/i2c-2/2-0063

Interesting files:

region - my (DDP) device says 2.

power_level - mine says 88 when active. You can echo higher values into it (according to the driver's source, it should be 0 or in the range 88-115). I did not check the effect it has.

region_bottom_frequency - mine says 87500, even though the GUI only allows 88.1 and up.

The transmitter is extremely weak. in my 07 Mercedes C230, the transmitter isn't strong enough to reach the antenna unless the phone is behind the rear seats under the rear window, OR upside down in the cupholder (which results in periodic static). Unfortunately 88.1 is the lowest frequency on the transmitter, but I can tune my Comand 50 to 87.9. Probably not going to be that useful unless your golf cart has a radio.

88.1 is right where I used to have Terry Wogan before he retired - Bracknell may be the same. I hit 'find' and watched the scan till I spotted a chunk where nothing was being found.

Once selected and tuned, my ford fiesta happily picked up signal from n900 on the passenger seat.

I noticed something oddly..

My car, which is from the 90s has a receiver that only extends once you turn on the FM radio. I find it hard to get a good signal from the front seat.

Yet the other family cars all have the shark fin which I don't have trouble when the N900 is with me in the front seat..

And they're all Toyotas. o.O But the one on my car is farther back than the shark fins.

I find many Europeans to be superficial and poorly educated. That is just the experience of a few years in Europe, though. Present company excluded, of course.

Lol. At least they didn't elect W.

I tested this out on two cars:

Acura RSX - 04
Toyota Camry SE - 08

In both car, the FM transmitter is definitely useless for the front seat. Once I put N900 behind the seat, then I could get clear sound.

BTW, no point of Fm Transmitter if you have to turn off bluetooth signal. My Camry has handsfree. I couldn't get FM signal as long as my N900's bluetooth is connected to the car.

I have an FM transmitter wire for the Acura. Therefore, I could just plug it into N900's 3.5mm jack for sound. It work fine. I don't have put the N900 behind my seat.

For the Camry, it has an aux port which I don't have to turn off BT.
