My radio in my SAAB 95 2001 will only allow me to use the steering wheel controls to control it. I removed the radio it was working fine, I removed it to replace lights in the ACC, when I put it back it would not work with the radio controls only the steering wheel? The fuses are fine and all the pins in the back are straight. I did pull the fuses to check them. I have taken the radio out before to change bulbs and never happened to me any other time. Okay so now the radio does not work at all. The lights do not come on when they should. No power seems like. I just do not understand how it worked before I took it out and now nothing? Any help please.
