I would have asked a few questions about my car radio. – Corsa B – Built.: 04/1997 1.) I have now installed a radio (don’t know which (brand: blue point) I can only turn on myself. Actually, I know this so that if I turn on the ignition, that the radio also concerns. But I always have to turn on and off my radio manually and that’s annoying. Which connection do I have to change?? (Please as uncomplicated as possible, because I’m not as experienced in it) 2.) I now have a new one. it bought radio from JVC KD-R301. I would like to connect this also tomorrow but my JVC has only 2 plugs but my blue point 3 plug. Do I have to change some cables now? I already tried to install the JVC today but it didn’t work. When I connected 1 plug, it went on briefly for 1sec afterwards but it went off again.
