anr to gpx

I just got a Nuvi 750 and am trying to learn all its tricks.
I normally use Street Atlas to plan my trips... I have 45k
on my motor home using SA and mostly use it because it is
very functional. I would like to be able to import the anr
files into the Garmin. I have tried using gpsbabel to go
from anr to gpx but I may be using the wrong options. When
I try to import the routes I get an error message saying
"too many vias" and it fails.
Anybody got any answers or advise??

I have a Nuvi 260 for travel,
and an old 12 XL for hiking.

I think the newer "car/travel" GPS models merely point you along the road,
whereas the hiking models have the capability to create waypoints, routes,
etc.

Since the hiking models don't follow roads, the "route" can be pre-plotted,
or breadcrumbed..
Since the travel models follow the roads, and the GPS knows the best
"route",
the concept of pre-defining a route kinda defeats the purpose of having it.

Some GPS units may allow you to pre-define some high level of routing,
or may limit you to just a single stopover "via" point along to your
destination.

oops - sorry - looks like the 750 can do it -
take a look at the other thread on NUVI 750 - Route Planning -

When you are creating routes in MapSource using the Route tool, using it
in the Auto-Routing mode and just clicking on spots, there is no
apparent limit on the number of via points you can put in the route. I
have used as many as 70 or 80 on planning long and complex routes.

But most GPS receivers have a limit on the number of points (either
waypoints or via points) you can have in a route. For my 76Cx is is 50
waypoints.

MapSource will upload routes to my 76Cx without regard for the number of
points in the route. And if I look at a route that has say 68 points in
it, when I look at it on the 76Cx it will have 68 points in it too. But
I I try to activate the route as a Follow Road route I'll get an error
that says "Only 50 points can be used for follow road navigation."

I can activate the route in the Off Road mode (point to point routing)
and it will list all 68 points in the Turn Preview and Route List pages.

So there is probably some limit like I describe above being applied to
the gpsbabel translation from anr to gpx.

I'm not familiar with the anr routes as far as contents and format in
the file but what you might try doing is to create a short simple route
with five via points or so. Look at that from S&T and see if it shows
or lists 5 points. Then run it through gpsbabel to gpx, import that to
MapSource, and see if they are still in agreement.

If may be that you'll have to play around with the limits a little and
limit the number of via points to 50 or less.

A side effect of all this, if you using a GPS receiver that will do both
Follow Road and Off Road routes, is that while you can activate the
route with more than 50 via points in the Off Road mode, the route legs
will all be straight line between points and the distances will be will
be straight line distances. So the route will be a lot shorter but you
would have to be in an airplane or something to travel it in that
distance. If you are following roads, it will be the distance seen in
MapSource.

I have S&T 2008 on my desktop PC and use it for find places and things
occasionally. But for the most part, since I have become adept at using
MapSource, I do all my route planning in MapSource. I have the
MapSource preferences set so that when I create route it numbers the via
points from 001 up sequentially. For some silly reason it skips number
in the sequence so I can't use the via points names to count the points
in a route but I can look at the Via Points column on the Routes User
Data Tab to see how many points I have in a route.
