What did I do? I'm fairly adept mechanically, but today I installed a SIR-GM1 receiver in my C6 vert and when I went to start it - nothing. All I get is a little click. In addition, I keep getting a display in the DIC that reads "no fobs detected". I turned the lights on and they seem bright. The doors won't open unless I use the mechanical release on the floor. I can't turn the radio on either. I really don't think the battery is discharged. What a bummer. This is one of the last nice weekends I'll get in Michigan before the snow starts to fall.
