Just bought a used 2005 F350 SD Pickup, base XL model so it only has the AM/FM radio.
Truck has 2 speakers in the doors. I want to put 2 more in the back. Factory wiring is there, I have looked. Manual says radio has a fader, but when I cycle through the radio menu, it only gives bass, treble, and balance. Fader does not come up. I can see the word 'fade' on the radio face, but it just doesn't light up when I cycle through.
Is it a faulty unit, or is there something I am missing? Anyone else experienced this?
Any help or suggestions would be appreciated.
