Hi. I recently had an Opel Omega. Would like to exchange the radio and have a few questions. First of all it is this radio:https://data.motor-talk.de/…/img-0531-4447060379146087677.jpg I can use the on-board computer,so I think only over the radio. There is a steering wheel remote control but this does not work at all.https://data.motor-talk.de/…/img-0529-9079918181211096001.jpg I assume that if I change the radio, the on-board computer or the petrol range no longer Is there anything on the display at all? Thanks already in advance for the help. Greeting Omega B,V94,BC,CC,CID,DZM,EFH,Benzin,Schlagung,Bj 2002
