Technical DAB Radio help

[Almu1]

Hi guys and girls

I fitted a new DAB stereo to my car the other day all working fine but I didn't have time to finish it off properly (fit the fascia or run the aerial round).

When I did get round to finishing it off the stereo works fine fully functional, but theirs no sound coming through the speakers. I've checked all the wiring and it's all connected properly.

What have I done to it please any help appreciated

Thanks in advance
