ok just a little bit of a weird problem, when i eject the CD all the lights and display text shut off, when i put a cd back in, it all comes back on. is this model suppose to do this, or have i wired something incorrectly?
hmm never used a 390mp. Does it have a removable face? Check the connection it is making to the rest of the unit and make sure it is secure on there. I have seen a lot of Sony headunits have a face problem with that connection but Pioneers usually are pretty reliable.
Is the unit actually shutting off or just the display?
