Hi! I recently installed a new 2DIN radio in my astra and it worked for a while but now it doesn't. The power source is that extra empty plug with CIG lighter. At first I thought it was a fuse but no, fuses are all good. Then I thought well maybe the plug itself is broken or the cable must be somehow loose, and again I was wrong. Now I noticed that my radio turns on for some seconds after I unlock the car. That means the power gets to it but for some reason not when the car gets turned on. The only thing I did was change the cars battery and it did something to this plug. Does anyone have any idea what I could do?
