I suspect that the current heads up display technology is a bit
rough for motorcycle application.  The way they currnetly work is
to have a box, about the size of a shoe box, with some display in
it which is columnated and bounced off a semireflective surface in
front of the viewer.  This sounds a bit clunky for a helmet mount.

As for storage, the only consumer system that I've seen is ETAK.
ETAK uses a CRT for a display and stores map info on (gak) cassette.
I noticed that National Car Rental at SFO had these available in
their cars.
