Hello. I have 2 full huts in my Astra G OPC. That means steering wheel remote control and a board computer with Navi. So the big color display. Now I can’t just change the radio because I can’t use my Navi anymore. Is there a way with which I can hear music from my USB stick at the same time, but I can still use my board computer and my Navi? I made something up. But unfortunately I don’t know if this works. I have an empty compartment below. So I have a CD storage compartment. Couldn’t you just put in a 2nd radio and connect the boxes from my car and the amplifier with the subwoofer? So I can listen to music with the lower radio and operate my board computer with the upper original. Or is that not so easy? I’m looking forward to your answers.
