Hello,

Check the fuse that's in the back of the stereo. It's possible that the fuse has come loose. If it is blown then that is a separate problem that can be dealt with then. Please check the fuse and get back to. We can go from there if needed.

Thanks,
Alex

All fuses looked good. To be honest I do not know how the battery died in the first place my lights are auto. Thanks for the help.

Hello again,

Okay, you might want to check the antennae wire. A lot of aftermarket stereos use the antennae wire as a ground for the stereo. Also check the power and ground wires to the stereo and report back with what you find out.

Thanks,
Alex
