I hear you. What timwatt said.^

First things first.

1. Start media player and pump out some sound. Shuffle all songs will do.

2. Once you're rockin' tap the top bar that says now playing and a drop down button menu will appear. tap FM transmitter.

3. From the bottom a new "FM transmitter" selection thingy will appear. Tap the box next to "FM transmitter on" and a check mark should appear. Forget about frequency for now...Tap "save" and the box will close and you should no longer hear any sound from the N900's speakers.

If you still hear sound then something is wrong.

Go through the steps outlined above again to see if that box you checked in step 3 is still checked. If it is and sound is still coming from the N900's speakers then that is one problem.

If it isn't, tap it again to acivate the check mark and go through the steps. If you are sure you are seeing the check mark and you are sure you are hitting "save" but it is not there when you return, then that is another problem.

Report back your results please.
