How come I can get phone calls,but I cannot listen to radio like I used to with another device,

The manual doesn't mention music, just calls. No fun listening to music in one ear.

..

during a call/while listening to radio or music, use the navigation button up and down to raise and lower the call or music volume level (this only activates during a call or when radio or music function is on)

I hope this was useful

It will be depends on your mobile brand....

Hi andyss651, The Xperia X10 does not have a radio tuner, so you cannot listen to radio via radio tuner. If you want to listen to radio on your phone you could use an application called shoutcast or go to last.fm and listen to radio over the internet as long as you have a data plan. Alex

You power supply is probably defective

check ur headset or speaker

Hi,could be low volume level.You can increase it with the button on the side.If no joy try use other earpiece,if nothing again then there's a device fault. You can try reflash firmware using Nokia PC Suite-Firmware updater.If after that not working then go to Nokia centre,if under warranty repair is free of charge.

Rate me if helped.Thanks.

Sould be fine as long as it is same connection into I phone?.
It is only an audio output and will not damage the I Phone.
You can now get a FM transmitter device that tunes into your FM radio and does the same job.

what headset are u using? i presume its the 's9', most connection problems are solved by disconnecting the headphone and then reconnect it.
or go to ur bluetooth devices on ur computer, and click on the device then properties, then services then, select all boxes. remember to apply the changes.
good luck

i think its a factory setting you cant change. you cant listen to radio without headphones.
