HI, I bought a new multimedia radio in the Inrenet because the dealer assured me that it is compatible with my Omega. Steering wheel remote control and BC would continue to work. I had told him my vehicle data: Opel Omega B bj.2002, NCDC 2015 Radio with Bose system, Navi, telephone, on-board computer and steering wheel remote control. Now the part came with a wire harness with Cuadlock plug which does not fit at all and a small wire harness, with which the device is concerned and also a I went to a specialist store and wanted to know what it would cost to install it. When he was listening to the Bose system, he waved off. It would be far too expensive and would be at 250,-€ – 300,-€. It must be possible to make something easier and cheaper, who can help me with it? I live in 40670 Meerbusch near Düsseldorf. mfg Burkhard
