I believe Incartec is very similar to the Dynamic Sounds kit.
It is plug and play with the new wiring kit and I found it straightforward. The new aerial has an extra wire for power which I connected to the blue/white wire of the Pioneer. The new aerial I fitted has a new base too which fits well - you need to remove the entire stock unit to fit it. I did not connect the speed sensor wire but did connect/clamp the handbrake wire. You will not receive full DAB without modification to the stock aerial amplifier unit, or by replacing it with a powerered DAB aerial.
I’ve written some more information on the install in this thread.
