The unit is completely voice activated.

I believe it will inform you of the name of the caller if you have it stored in its phonebook. Otherwise, it just informs you that you have an incoming call.

There is no callerID display with this device.

It's not a hard installation, but does require a steady hand and sharp cutting tools.
