Well whats if worth?

This is the ideal upgrade for the CDC 40 opera or any other compatible HU

Hopefully you would have the wiring already in the harness. My car did not so I made the harness myself. The HU will need to be Tech2'd to tell it the DAB box is fitted. I know the Aerial is £100 at VX and the DAB box is even more. I would think you would have to pay over £200 for these two items.
