Hello, I wanted to ask if one of you has replaced his original work radio Navi 650 (with color display) with a Pioneer radio or something like that? A competent employee of ARS24.de said that it is not possible for this infotaiment system to replace it with another, because “it is deeply integrated in the vehicle electronics company”. But I can’t and don’t want to be completely glimmering. However, there really is no CAN bus adapter that explicitly uses for the Navi 650 we rden can. There is only the 42-HVX-301 and this is only compatible for Opel model with CD300/CD400 (without color display). Or does this adapter work? I hope you can help me.
