Does anyone know how to change the display color on a Clarion ARX6170R
car stereo?

It is an old stereo and the two green bulbs behind the LCD have burned
out.

I opened the panel up last night and noticed that there is another set
of lamps which appears to be orange. The LED:s that illuminate the
buttons also appear to be multi color so I figured I just switch to
the other color, which probably would match the red illumination in
the car much better.

Unfortunately I have no users manual, and I have tried to figure out
how to change the color without it, but have failed.

I bought a manual online, which just arrived, but even though the file
name indicates that it should be for an ARX6170R, it is for an
apparently simpler ARX3170V/E, that does not appear to have selectable
display color :-(

Thanks,
Thomas

Called the distributor and got the correct sequence.
