I just installed the unit. I did factory reset under setting. The FM/AM radio does not work. Also, the lights on the buttons do not light up.

One thing I notice is the "Key Light" Icon under setting disappear.

Can somebody help? I may erase something in the memory of the unit when I did factory reset. If you have the firmware, I would appreciate it if you can send it to me.

or Do I need to connect the orange wire called "Illumination" to anything?

Thank you
