Question about Pioneer DEH-P4800MP CD Player
Turn off Radio with car on or key on. Press and hold the big volume button in for 3 seconds, and the radio will say initialise. Than press the FCN button till it says AUX. Than press the SEL button till it says "Aux ON ". Turn on radio and you should be good to go.

While you may read over a million answers to this problem, try this one first:
With the KEY ON, POWER THE UNIT OFF, by pushing the volume button IN for 3 seconds.
After power is off and key is STILL ON, press and hold the volume button AGAIN for 3 FULL SECONDS. The elusive "Initial" settings should reappear at this point. To get out of INITIAL SETTINGS, simply press again for THREE SECONDS, or press "BAND" to "escape"...
I hope this helps.
