Almera 1.8 Sport bought – built in radio?

Hello guys, I’m new here. I’ve had a new car since yesterday, changed, after four years VW Polo (45 hp) I’m finally driving a 2001 Almera 1.8 sport. Dream car, so far more than satisfied, the beautiful Japanese is just doing great. However, there is a little detail that bothers me. I would have liked to take the MP3 radio from my old car. In Nissan this tape radio is installed in the middle console, without CD changer. Now I can this radio yes The compartment under the center console, where the CD changer would be normal, is empty. Can I install a radio there? Somehow you should be able to take the compartment out, and maybe also somehow get to the wiring behind it. Or do I see the whole thing wrong and have no chance on another radio? Please help me and give me tips Greetings, Andreas
