I use voice commands a lot as I find using the system safer than poking around for buttons when driving, but I've just noticed that when tuned into the DAB wavelength, if I use voice command to change stations, e.g. from Capital to BBC Radio 4, the station is tuned ok, but switches to FM. Does anyone know if this can be rectified so that the station changes, but remains on DAB? I've checked all the voice commands in the handbook, but nothing seems appropriate.

I also find it strange that there's apparently no voice command to turn off the radio etc.

Any comments would be much appreciated.

Cheers.
