Peugeot 407 Multifunction Display Replacement

Hello.

My Multifunction Display fade out when hot.
The Peugeot original is pretty expensive, so i wonder if there are after market at good guality? I have seen many of them, but on some the text and symbols seems to have a slightly different design. I have also read somewere that som function may be lost.

Is it difficult to repcace them? Peugeot told me that it have to be coded?

Thanks.
