Is it possible to add DAB AND ipod usb to Concert II ?

[F1ux]

I have an A4 with the concert II. I'd really like to get DAB and also have my ipod work and be controllable by the steering wheel.

I've seen dab units and the connect2 addon for ipod/iphone.

Can you use them both though?

or should i just dump a load of cash on a new headunit.
