Ducato stereo problem

[ryanmartin104]

I recently bought a 2012 ducato maxi that had a taco placed in the stereo area. I found a stereo unit from a boxer at my local crash repairs place i have tried to fit the stereo but am getting a code error on thestereo unit screen. I have go all the codes for the stereo but cant get past the code error sign. Any help would be great.
