ive found a aussie forum where some guys have hacked up some mainstream GPS software, to take local maps, and i think there is an open source NZ map i can import into that hacking...
i have one running its got maps and is a journey logger with waypoints, but its old and rather crap. no good for navigating with
and short of spending $250+ on a program and map, that i have no idea about...it might take a while.
the carputer system itself is good, and ill guess i'll just keep tweaking little things till im happy of have broken it
might pull some amps, x-overs and some 8" subs (great mid bass) out of storage if i feel bored one w/e at home, and go crazy.
