Citroen jumper dab

[Matty21]

Hello I have a Citroen relay/jumper with the dab unit it was working once upon a time now if I select a station it’s says station is unavailable only the bbc stations work. Dab works in the other vans I think it needs a update but not really got time to take it to the dealers? Is there anything I can do miss dab

It could be an aerial problem or the DAB tuner. Hard to say without further info. An update won't fix this sort of thing - something else is going on.
