Yep, while it can override a local station it's much nicer if you just scroll slowly until you find an empty channel to use! (Toyota Echo 2004 as a test)

I had no luck trying to use it for music in my '99 Mondeo in Oxford, UK - nor in Milton Keynes - nor in Weybridge.

I got sound, but it was always very staticy unless I held it in the space in front of the windscreen, and then it was clear. But that isn't very safe when driving The car's antenna is on the roof at the front so I had expected better.

It's hard to be sure, but it might be because i couldn't find any frequency in it's range which didn't get interference from some broadcast or other. I literally tried every 0.1MHz increment on the N900 and the car radio, and from time to time some other boadcast would fade in. The most powerful broadcasters (BBC) spanned nearly 2MHz if you include low quality fading sound from them

When it was on the passenger seat, I got sound some of the time but it was almost always too staticy to listen to.

My car is too old to support Bluetooth audio, and with the N900 costing as much as a cheap second hand car that's now out

I was fine till I got a bit close to the coast - think I may have been close to the coastguard frequency. Oops!

Around the rest of the county I was fine. Will find another frequency when I have time to hunt.

That's been reported as a bug and should be fixed in some future firmware, not necessarily the next one.

Or it might be limited on a per firmware localization basis? IIRC this is how the Wifi channel restrictions are also applied.

Perhaps people reporting their performance should mention their firmware localization?

I'm on US firmware, and have had pretty decent success with it in multiple vehicles. I have no familiarity with other FM transmitters though.

i my case it taken my alot of time to be able to fint a frequency, with no many signals. Finally I found that 101.1 fm worked very fine. And I use it all days i go by car.

FM Transmitter is working fine for me for music purposes, but today I was driving in the car and had the phone in a stand, but even though I had the volume max high, it was hard to hear the other person. I had a sudden idea to try FM Transmitter for it, but it didn't work. Wouldn't it be a nice speakerphone workaround?

its not so great, ive tryed using it many times and ive had to switch frequenices often, and the only way i can get the best reception is if i leave my phone on the sun roof.

[fm transmitter not working when usb (charger) is plugged in]
It's actually fixed in the upcoming firmware version, according to a link in that other thread about the new firmware.

Uhm, I just tested it on 51-1 and it didn't work. As soon as I plugged in the USB cable to charge it, it stopped the FM transmitter.
