Renault Trafic bj 2003 double din radio installation

Moin, I’m only sporadically active here but still I don’t think a performance is necessary anymore. I have to say that I’m just a little overburdened. Usually such banal topics are treated to Hauf in forums but I didn’t find anything at all. Well, yes. So I want to install a double Din radio in my Renault Trafic. To do this I definitely need a new slot box. That’s where the problem started. There are tens of different ones, most of them starting in 2011. On Go ogle result page 4!!!! Did I then find this: https://www.adaptershop.de/…/…versal radio mounting frame::234.html Is that right? Then the next question, I certainly need an adapter on Iso, right? Which one do I need? Do I also need phantom feeds or something like that? How does this work with the steering wheel remote control? Which Can Bus adapter do I need? Have only louder and quieter. Radio should become a Clarion nx502e. Is there anything else to consider? h feel like an idiot, my Ford didn’t take ten minutes to collect all the info. Hope you can help me. Best regards Jannik
