Audio 20 (w203) removal

I have a audio 20 unit in my c class (w203) 2005 that has developed a CD ERROR (it won’t accept a disk) and my local MB dealer want £120 to take a look at it so I would like to remove it and replace it with a identical model I sourced from fleabay
My question is will the new unit work when its installed or does it need reprogramming or coding, any tips on removing the audio 20 unit would be very welcome
Thanks in advance and again sorry if this has been posted before on this excellent forum
