I'm trying to use the N900 FM Transmitter in my car.

It seems it's emitting a periodic beep every 5 seconds or 10 seconds or so... Otherwise the signal is good, but the beep is annoying...

If I use an external transmitter plugged into the earjack on the same frequency, no beep is heard, so it's no external beep.

Anyone know what this could be? Or is it maybe that the signal IS too weak and the beep is from the car's audio system signalling its weakness, while with the external FM transmitter the signal is stronger?

It's to tell you it's still alive and transmitting. Start sending audio and it'll stop.

Problem is it doesn't stop. I'm sending audio and it's beeping throughout.

Can I disable it manually?

Are you trying to transmit audio to a taken fm station?
You have to try and find a vacant one in your area , that is probably it .
keep us posted if it fixes your problem .

I think its supposed to beep to tell you that its still alive and transmitting. It should stop or at least be inaudiable when playing music though..

It only plays when theres no Audio for me, and then after a short amount of time the FM Transmitter turns off, which does get rather annoying.

Playing audio how?

I play audio through mpd, it's transmitted, however the beep is mixed in.

I don't wanna use the internal music player for audio, so maybe it'd stop if using that. That's why I'd like to disable the beep manually...

Maybe mpd is sending audio, but failing to set a flag saying "I am an audio player (so pause me when the phone rings)".

I don't know that any such flag exists, this is just speculation.

Yeah, something of this sort is happening it seems, don't know whether it's dbus or whatever, that should be notified, and then stop the beeps or what have you.

So it seems, I either need to somehow set the info, that audio is streaming, or turn of the beep by hand, either of the two.

The question is how?
