Hi Simon,
I am in the same boat, its taken me ages to figure out how to setup the DAB stations at first all I could find were BBC stations but now got some more, but I am off on holiday for two weeks so have to wait until I get back so if you find out the answer to you question in between time then please let me know a I will need to do the same, or i'll just check your thread to see what replies you have had.
