Buddy gave me the unit. No wiring instructions, only the leads. Spearkers n ant self-explanatory. Others?

well to give you a quick run down of wire colors:
red: hook to an (fused) ignition wire. pos. (+)
yellow: Goes to a fused constant wire (battery works)
Black: is a ground (-) hook that to the chassis
blue: Amp turn on output (+)... that goes to an amp
the color pairs i.e. white, green, purple, gray are for the speakers, the (-) is the the one with the black stripe... what else would you like to know?

Can we stop it from changing color

Hello bd1340,

The JVC KD-SC500 ships with the color selection set to "ALL DEMO" which alternates the colors approximately every 6 seconds.

To cancel the "ALL DEMO" and select a single color display, go into PSM mode by pressing and holding the SEL Button until the display changes. Use the left/right rocker until COLOR is displayed. Turn the VOLUME knob to select the color you want: Blue, Ocean, Purple, Pink, Rose, or Red. Press the SEL button again to exit PSM mode.

Hope this helps.

What is the orange wire for on the pioneer DEH-2800MP?

If you have a blue with white on it or a solid blue lead, I'm at a loss, however the manual even states that colors may change w/o notice. Best way to tell is to use a meter, black probe to ground and red probe to the orange. Put it on DC voltage then turn the ignition to acc. then turn on the deck, my hunch is that it's your amp remote turn on wire for an external amp or it can be used for a power antenna. Voltage should be 12.2-13.8dcv. Hope this helps

2nd display background changes from black to white at intervals


The change in the backgroung color of the OEL display is totally normal. This funtion lets the display works in two modes rather than only one to prevent OEL display damage, it is like a screen saver. I had the same model I bought

Wiring Problems

You didn't cut the plastic connectors off the factory wiring, did you? One is gray and one black.... if not, just get to a stereo shop and buy a wiring kit for your car and all colors will match. They're about $10. If you DID..... well..... we have a LOT of work to do....

DEH-P670MP Display goes from regular to extra bright, then back

Your deck has "reverse mode" activated. To turn it off, just turn off the power by holding the source button. The press the preset "5" button. When you turn the deck back on, reverse mode should be disabled. (If this doesn't work, try the same procedure with button "6". One's for reverse mode, the other for demo mode, but I'm not sure I remember which is which).

Pioneer deh p730

Has it always been like this? I know that the display inverts automatically to save the life of the OEL...otherwise the brightness of the same pixels being on all the time will cause the OEL to 'burn-in' If that isn't the problem, the OEL is going bad. They can run about $100 and usually aren't worth repairing.
