MapSource "route avoidance" info vs. receiver route

If I go to the trouble of entering route avoidance data in MapSource
(road construction, Interstate bridges that have fallen in the
Mississippi, that sort of thing), create a route and then upload it to
my 76CSx, the route avoidance info isn't sent, so when the receiver
re-calculates the route, it happily tries to direct me onto the closed
roads.

How do the special-purpose automotive receivers handle this?

I've never even laid eyes on a Nuvi or any such thing, so I don't know
how you get routes and waypoints into them in the first place.

Route avoidance lives in software, it is not part of the information or
data in a route. A route contains only a list of via points. When the
route is activated the local setting and preferences are applied to
getting a route that passes through the points in the route.

MapSource has two kinds of via points. There are waypoints and there
are map points or map lines.

Waypoints (they belong to the user and are uploaded with the route. And
they can be edited and have comments added to them by the user.

The map points and map lines belong to MapSource for all practical
purposes. You cannot edit their properties. They can be deleted from a
route or replaced with others but the specter of "these belong to
MapSource, not to you, looms over it all.

When routes are activated, the software in MapSource and on the GPS
receivers seems to consider that map points/lines are optional and can
be replaced with others if it considers it appropriate to using the
mapping data that is available and satisfying all the settings and
preferences.

When route with waypoints are activated, the softwares seem to consider
it a necessity to pass via those points and will always route you via
them.

When you create routes, clicking on the map with the Route Tool creates
a map point or map line. If you want to define a route with waypoints,
you have to place waypoints with the Waypoint Tool and then click on
those with the Route Tool to create the route.

If you have a route that is made up of map points/lines you can create
waypoints at the map point/line locations by clicking on the map
points/lines with the waypoint tool. It will not put the waypoints in
the route but you can open the route properties, insert the waypoints
(in the proper sequence of course), delete map points, and then have a
route with waypoints instead of map points.

So if you create the route you describe with waypoints, I think you'll
get the same result in MapSource and on the 76CSx unless there is a
difference in setting or preferences that precludes that.

Yeah, I know I can do that, but it makes the "auto routing" function
in the receiver less than useful for many trips.

I'm not sure I understand that. You are trying to get the same routing
in both places, using the same settings and waypoints instead of map
points is more likely to give you what you want, and that makes it less
useful?

Did you expect to open the box, fire it up, and get what you hoped to
get without any further intervention on your part? If so, the stuff
does not work that way.

Jack,

I think what the OP is looking for is the Custom Road Avoid feature that
the 2610 has. Unfortunately, the 76CSx does not have this feature. He
is saying that auto routing is less useful for many trips because he
cannot set a custom road avoid in his 76CSx once but has to manually set
waypoints in various routes to avoid a particular stretch of road.
