Hi,
Thanks for the reply - are you sure it fades the native HU *radio* during app voice commands? With the un-jailbroken Appradio 3 you can "mix" app sounds with the radio when the radio is playing but it just literally mixes, and at a fixed volume (which you can adjust but is never right!). If you are playing music through an app then it does fade the music when tomtom commands come in - but I think this is because when you are playing music through an app the music is coming over the bluetooth stream.......I'd be really interested to know because otherwise I might ditch this unit.
