Hello, Mike,
I was not baiting you. I probably was confused and was thinking about the
price per state of maps for one of the GPS units that can be attached to
your product, and I was not confusing dollars and yen. Map sets here are
much more expensive than 250 yen per prefecture. Think about 10,000 yen!
You may be right in saying that single CD map sets are clearer and more
detailed than multi-CD sets. However, my GPS mapset covers the entire US in
one CD, as I said before, and certainly seems to be clear and well-detailed
to me. But, as I also said, that GPS mapset cannot give a location for a
house address. It can find any place that you have the coordinates for and
give you the coordinates of wherever you are. That is its purpose. As I
said, it would be a little clumsy using that Garmin mapset in trying to
find specific addresses.

Not sure if I am being bated or not. Individual state maps are not
available for the BrailleNote GPS at any price. Certainly not $250 per
state as you mention in your email. Maybe you were mixing up dollars and
yen.
Maps for the BrailleNote GPS only come as a bundle for the entire U.S. as
part of the complete package. As most of you know, the list price is $1399
including all of the U.S., software and GPS hardware. The individual states
cannot be purchased separately.
Be aware when purchasing map data that one CD of maps does not have as much
or as good of quality data as 8 CDs of data. There are various compression
schemes which reduce the space required for map data. However, maps
designed mostly for highways or those without street addresses obviously
take a lot less room. This can be fine for some applications. This
difference in data quality and quantity accounts for much of the difference
in price between commercial products that cost $250 and those that cost
$800 and up.
