Remove a road?

You forgot "obssess over this until your head explodes". From some
things I've seen here, that's clearly an option for too many people.

Saw you are on a long trip. You check the road reports and you find that
a certain bridge is blocked due to construction. You GPS doesn't know
this, you know this.

If you know this as you start, you can "aim" right away for a different
bridge and reduce the detour (and traffic).

If you cannot tell your GPS that the bridge is unavailable, it will
insist you drive to it and during that time, you'll get useless and
constant messages from it telling you to turn left, right, u-turn,
everything but follow the road you manually plotted to avoid the closed
bridge.

If you could tell the GPS the bridge was closed, it would then be able
to plot you the next best route.

Generally, once you're "close enough" to the alternate crossing, the
receiver will re-calculate the route and stop yammering about the
original.

Still, it would be nice to be able to be able to tell the receiver ahead
of time that there are closed roads or roads you just don't like to
drive on.

MapSource can maintain "route avoidances" but doesn't pass that info to
the receiver, or at least doesn't pass it to my 76CSx.

Are you sure about that, Bert?
If the route avoidance features are used in MapSource and autorouting is
enabled, would not the MapSource generated route be passed to the 76CSx? (my
machine as well)

Mind you, I plot complicated routes manually with MapSource since I know
that neither it nor the autorouting in the GPSr will find the fastest route!
(I only do that on routes where I know the best way, but don't drive them
often enough to get them memorized)

Unless there's some trick I don't know about, yes, I'm sure.


Routes that are generated by MapSource are essentially ignored by the
receiver, since it only sends the waypoints that the user (me) enters,
and none of the automatically generated intervening turns.

Even if I have comprehensive route avoidance info in MapSource, if I
enter just the start and end of the route and send it to the receiver,
the receiver will happily re-calculate the route, using roads in the
route avoidance table if it's so inclined.


I can create vias with the routing tool or add additional waypoints by
hand, but then what's the point of having the route avoidance data if it
can't be used?
