I've noticed that on my f910, when listening to the radio or dvd the satnav voice comes from the front speakers, at a comfortable volume, but when listening to the usb or sd card the voice guidance comes from the rear speakers, and very loud, so loud that i have to go into the menu and reset the voice guidance volume to a lower level, then reset it back up louder again if i go back to listening to the radio.

Is there a way to get the satnav voice to come out of the front speakers only or all speakers whatever the source ?

 

Thanks.

Paul.
