Hi Damon,

the whole GPS thing completely confuses me now.
Doesn't take much <Smile>.
OK, when you start out, you first connect to your GPS system, via Bluetooth,
and the unit then automatically goes online, you don't even know it if you
set it up right, and downloads your current position, and the route you have
just created. You can either create the route, before or after you connect
to the receiver, but you are not online until you hit the calculate route
button. Once you hit that, it plots a route from your GPS position, to your
destination, by downloading approx. 5KB of data. It then plots your route.
If you go 80 metres or more off-track, your Wayfinder, will go back online,
and re-plot your route from yo9ur current GPS position. This is what makes
it better than Trekker and such, because Trekker does not automatically
re-plot your route, you have to ask it to do it.
As for bus stops and the like, if you have a good GPS signal, and this is
not guaranteed in a built-up area like London, then you will be warned of
your approaching bus stop, first two miles, then one mile, then 500 yards,
or feet, depending on your settings, then 200 of that unit, then 100, then
finally, you will be told you are at the destination.
Yes, it works very well in cars, I have often navigated my dad around in
unfamiliar areas using it.
Hope this helps.
All the best
