Your iPod lead is probably pluged into the CD changer socket so you may need to press the "CD" button twice.

The removal keys for this unit are not the usual "U" or "HorseShoe" keys. Disconnect the live feed before starting.
You require the Pioneer removal keys to avoid damaging the unit. Your local accessory dealer may loan them but cheap enough to purchase. Once the unit is out you simply gently pry at the locking tabs which retain the cage into the dash facia. I normally use a firm electrical screw driver for this part.
Remove the loom and antenna etc. from the cage connectors and it should be free

But to answer your question, the clock can be set like this.
  1. Press FUNCTION until clock comes up. Select it.
  2. Press the arrows until the segment of the clock you want to change is highlighted.
  3. Use the up and down arrows to set the clock.

???

1. Is the head unit powering the speakers directly or through an amp?
2. What ohm load (4,8,) per channel and how many speakers?
3. Does it do it with the bass set all the way down?

If you have access to a voltmeter see what the voltage is on the yellow and black wires when it is diming. It should be stable ~ 13.5v with car on. if its < 10v when dimming either there is:

1. Shorted speaker lead.
2. Bad ground to radio.
3. loose power feed to radio.
4. Ohm load below 4 ohms, causing the eccess current draw.

That error is (Format Read Error). Usually a MP3 problem when the disc was burned too fast, or corrupted during burn. Some writing programs dont put an initial track on the CD designating it an audio disc. I have seen Nero have many Problems with this. FYI
Try burning 1x speed on the next disc, yes slow, just to see if it works. If so then gradually increase the burnning speed up again.

Unfortunately there does not seem to be an LCD brightness adjust on that old really nice car stereo. So what it is is that the LCD screen uses (Electro Luminescence) technology which well fails after so long. (In fact your stereo is not engineered to last that long by any means. Check the link/thread I sent there may be a replacement part available but I highly doubt that is worth the cost/risk.

Check the connections for the aerial to the device. If they are good and the aerial gives out a good signal then there's an electrical fault on the unit.
