In addition, you would also need a DAB antenna and possibly, depending on the car, a bezel and, if you want it, an FM plug adapter etc. Because all this is not included with the radio itself. The radio does have cables but these are from accessory radio to ISO plug and the adapter cables then go from the original radio plug to the ISO of the accessory radio.

I have the radio in a T5 California.
It uses the ISO plug. It actually fits with the accessories.
But as already described by Janik, you need a DAB antenna.

If you didn't have an accessory radio in the car before, you will almost certainly need adapter cables. I had it installed in a Subaru and needed adapters. I contacted Exclusiv Car Hifi for the cables and they told me exactly what I needed and sent it to me the next day.
