I am a new and proud owner of a 2nd hand 2008 Sorento Titan which has no instruction manual for the car radio. Indeed, I cannot find details of the car radio on the web. It is branded Kia and JVC and has DAB written next to the FM button (the AM button is below). However, whilst I can get FM and AM stations, no button I press brings me to digital stations. I would have thought DAB indicated 'digital', or am I mistaken?
