    Was this radio a new install or has it worked before in this vehicle??

    What car is it in? Do you have "premium" factory sound system?

Sounds like a possible ground issue. Check your ground (very important). Also try running the red wire to a keyed source i.e. from fuse block. Then run the yellow to a constant 12v source i.e.battery.

James, sounds like a defective power switch. If the wiring were wrong the unit wouldn't power up at all. You may make a confirmation by swapping face plates to localize the fault.

No display

Did you install the unit with the correct wiring harness, or cut-and-splice the wires from the factory line to the stereo lines? This could be a problem.

Time setting

Make sure unit is off by pressing and holding the 'Source' button. Wait 3 seconds, and then press and hold the 'Source' button. Do Not Release the button! A display reading "Initial" will show. Then use the arrow buttons surrounding the 'Source' to set clock. The 'Function' button isn't involved, dispite what the manuel states.

Car radio not working

Sound like you need the manual to this radio, I would have said that there are components inside that go bad that will cause a radio not to light up in the display area. But if you radio is saying tuner, and maybe cd then it would be the selector button that has a problem. Or no antenna is hooked up or come apart.

Bad face plate!

It may be the flexible connector link connecting to the drop down faceplate.

Pioneer DEH-P4800MP - Can not get into INITIAL mode to change settings

Actually, TRY powering OFF the unit, and release the volume button. Then, press and hold ONLY THE VOLUME BUTTON, until the initial settings appear. Pioneer really needs to get their act together on this issue. I have read all over that MANY people have had this issue, and the website is just a repeat of their lame printed manual.

Hope this helps. In review:

From OFF, press and hold ONLY THE VOLUME BUTTON. The initial settings shall appear at this point after about three seconds...

I just read these instructions, and while trying it, I found that my FUNCTION KEY had ABSOLUTELY NO FUNCTION IN THIS.
