Thanks again for response. Only options I think I have is to send unit back or add a dab unit to get stations. Unless some bright spark can come up with a solution
Option 1 is to ask the manufacturer of second radio to add code to activate the antenna with canbus. All Punto since Evo would not work with this unit.
Other option, is a lot of work, is to replace your antenna with a Grande Punto one, and put a wire from your unit to the top rear of the car where you have antenna. Not very easy I think
