During my install of the SWI-PS I had some issues...
When I powered it up, none of my buttons lit up. Then illimuniation was non-functional and my gps had no signal strength.
So.... I ripped the entire dash apart thinking I forgot to install my antenna cable, and maybe damaged my illumination wire....
This is what is was, my illumunation color was set to memory 2, and apparently when the power is off this unit, it must clear out some settings, and it decided to leave it set to memory 2 but it had no color. As soon as I selected another color the lights came back on. Whew, though
