I have a 2008 c.c. just had pioneer 4200 dd ,hertz hsk 165 speakers,massive 5 channel amp and 2 kicker cvt 10 2 ohms.I have non bose but i do have s/w controls and onstar.I have the pac and axxess integration devices but i have to have my headlights on for the radio and s/w controls to work right.The cd player will still work.What could be the problem?Its been to the stereo shop twice.

 

It must be the s/w module , it must be getting power from the ilumination wire instead of the ACC wire.

 

It will work at night and if i put something over the sensor thing on the dash it will work during the day.Thanks for the advise 08cheyennesc.
