ok, so it DOES work just like with other phones.
that calms me down.

I noticed that in my cars mitsubishi eclipse and nissan versa hatchback that if the n900 is strapped to the ceiling of the cars I get a very good reception. But I have to figure out a way to run the charger cable. Would it be possible to use a 8 foot usb extension cable to get the length I need to hide the cable? I think the max length to transmit data is what about 15 feet without having to boost the signal? But i will be just supplying power. I'll figure something out.

Hmm is the only way to use the fm transmitter through the media player?

I think that once activated, all device audio is broadcast via the FM transmitter.

"I think that once activated, all device audio is broadcast via the FM transmitter. "

Yes it can be activated from general parameters for example

[QUOTE=cddiede;396048]I have an E320 CDI, on mine, there is a connector in the glove box for external audio. Can you use the TV out cable to connect to that?

Yeah, I would love to do that, but I didn't get the external audio option on my car.

The worst is when you manage to find a frequency that isn't being used so you get a nice sound coming through the cars speakers and then you actually drive somewhere.

It then wrong especially when you are not staying locally because as you drive radio stations decide to use YOUR frequency.

I have not tried this on the n900 but I imagine if you lived in the Antarctic or somewhere else as densely populated it work quite well. However, if you live in a large city with lots of commercial and pirate radio stations then save yourself the hassle and just don't bother.

Maybe you could do something hackish like attach a piece of wire to the antenna then feed it inside the car - so that you effective have an internal antenna.

Of course it would be even neater if you did that to the antenna connection behind the car stereo. If your car has a removable stereo it should be possible.

I know under the right conditions even the cheap iPod transmitter I bought off eBay can easily drown out local stations so it shouldn't even be a problem if you drift in/out of range of REAL stations using the same frequency. Its all down to how well the stereo is picking up your transmitter vs the real one. Obviously if its struggling to begin with then the real station is going to easily be stronger.

If you really want it badly enough you could completely disconnect the external antenna in favour of rigging one internally in the car but then you might lose reception of real radio stations, as you would have the reverse problem.

Not at all. I have the feeling that playing through the speakers would drain battery faster than when using the FM transmitter.
