Loads of people are starting to get GPS stuff
in their cars. I really want this, but I don’t want to pay a lot. Aldi
were doing a thing that was a GPS receiver and
a PocketPC, so you could use the PDA as a
PDA and then plug it in when you were in the
car to have it do GPS —it spoke to you and
told you where to turn and so on.
I think this should be doable with a Zaurus. You can buy CompactFlash
GPS cards, which will plug into the Z, so that
would work fine. What’s missing, however, is the map data. It seems that
there isn’t any freely available vector map data which a navigation
program could use. Damn. (You need vector data, not bitmap data
(pictures of maps) because in vector data the points where streets meet
and so on are identified. Computers can’t do a lot with bitmap data
other than display it; they can’t interpret it.)
I wouldn’t mind the idea of buying some map data, if that were
possible. Has anyone done anything like this?
