DAB Radio issue

[Gizmo2155]

Hi,
I just bought a 2011 XC60 (Never owned a Volvo before)
It was listed as having the premium upgrade audio system in it.

When I select radio I get the following options on screen:

AM
FM 1
FM 2
DAB 1
DAB 2

If I select AM, FM 1 or FM 2 then press OK it goes to the relevant band and I can select radio stations.

However, when I press ok on DAB 1 or DAB 2 nothing happens.
Does anyone have any idea what the issue may be?
Could it be that despite having the options on screen that DAB is not available on that unit?

One other issue I have is that I get no sound from the front driver side speakers, at first I suspected the speaker itself but as there is no sound from the tweeter on that door either I am concerned it is more a fault with the radio itself.

Any help would be appreciated
