I've never seen that problem in a unit in a car, but I have seen it become
an issue on display boards. My rep said we should leave it off in a car,
but on in the display.

The reason that ALL the units with the OEL display do that is the OEL
suffers from a phenomenon similar to burn-in on a CRT, so the designers
set
the unit up to reverse the display on a 50% duty cycle so that all the
cells
wear the same.

My bad, I meant "reverse" mode. If that's not it I don't know what it
could
be. My wife's 740 has reverse mode turned off, but when it's on it
works
all the time, not just when the radio's off. Push preset 5 with the
unit
off and that will disable it. Good luck.

This is not the demo mode...I have the demo turned off. It is just
two
different backgrounds for the clock while the unit is off and the
vehicle
is
on. It is very annoying when it goes from the solid black background
to
that
bright pink and blue one.

is.
That will disable the demo mode. All of this is in the menu.

I have one of the new Pioneer DEHP7500 head units and have one
complaint. When the unit is off and the vehicle is on the time is
displayed in a black background with white lettering. But then it
changes to a pink background on about 80% of the face and blue on
the
other 20% and displays the time on that background for a few...how
do
I
make it quit switchiung back and forth???
