Yes it is possible, but after removing the CN+ you will not be able to change any of the vehicle settings such as: date, time, mph or kph, mpg or l/100km, auto door locking at 20kph, independant driver's door unlocking, independant boot unlocking, buzzer volume, temperature units ºC or ºF etc.
You can overcome this by carrying out the Proxy Alignment procedure which will tell the car's body computer the CN+ has been removed and the setting functions will then be available on the MODE button menus.
