Hi

I have a Corsa with a Delco CDR500 with a minor fault (related to power and
seek circuits).

I've just got hold of a newer unit (still Delco, same model number) out of a
'99 Vectra, which has the two-line matrix display.

I can't get the new unit to adjust to the smaller display - is there a (not
in the manual) way to set the display type? I opened it up and there doesn't
seem to be any jumper settings or dip switches.

Any help appreciated.
