How do I avoid duplicate waypoints and why does my Zumo ignore them anyway?

Former Member over 10 years ago

Fairly new to Basecamp although a long time user of Mapsource.

How do I deal with and avoid duplicate waypoints?

It seems that every time I use a waypoint in a route it gets a new name.

For example I have the Calais ferry waypoint as "Calais". After a route planning session for a few trips I now have "Calais", "Calais1", "Calais2" and so on. These also end up on my Zumo.

Further to that the Zumo seems to ignore them anyway!

On a recent trip to Spain I set a route to Tours via Rouen to deliberately avoid Paris using Rouen, Evreux, Dreux as waypoints. The Zumo tried to take me down the A16 towards Amiens rather than the A28 to Rouen so I ignored the instructions. Perhaps it was trying to get me back but the Zumo then ignored all the other waypoints I had set up and seemed intent on taking me to Paris.

I double checked the route and all the waypoints were correctly set.

When we finally got to Tours we had no other problems all the way to Spain but on the way back it did exactly the same thing as soon as we got north of Tours and ignored all my waypoints and tried to take us via Paris again. Bizarre....

Any ideas/suggestions?

Thanks

Well without knowing exactly how you planned the route I don't know, but we use that route to Tours regularly and my nuvi navigates it with a route created in Basecamp without issue. What routing/avoidances did you have set?

Also without knowing exactly how you are creating routes/sending them to your Zumo it's difficult to confirm how/when the duplicates are being created. Are they appearing in Basecamp? Or only on your Zumo? Or both?

Thanks.

I planned the routes on Basecamp by "create route" and dragging the start and end waypoints in (i.e. Calais and Tours) then dragging the other waypoints into the route. It displays perfectly in Basecamp and on the Zumo. Then I started another route and used Calais as the start point but it seems to create a Calais1 at that point.

When the routes are copied to the Zumo it takes all the duplicates as well.

Avoidances are unpaved roads, u-turns, narrow tracks, seasonal road closures.

When I get a chance I'll do a screen grab to show what's happening.

Which Zumo do you have as there are issues with the 600 series and Basecamp.

A 340.

...there are issues with the 600 series and Basecamp.

The routing issue with certain Zumo's has nothing to do with duplicate waypoints. There issue there is routes being constantly recalculated in the unit when navigating.

BaseCamp often duplicates waypoints. MapSource overwrites them. There's a way in BC to avoid that but since I use MS I don't recall how to do it off the top of my head.

Yes, agreed, that comment was aimed more at his routing issues, where the suggested work around for 600 series Zumos is, apparently, to use Mapsource :) However as he has a 340 it doesn't apply.

Been tied up a bit today but can now give some advice on duplicate waypoints. I find what works for me is to gather all the relevant waypoints into one list in Basecamp, then create the routes in that list. That avoids duplicates being created within the routes in Basecamp. Now send all the waypoints and routes in one hit to your GPS (in my case a nuvi) and that should avoid any duplicates.

I'll have a go at that.

The point about the 600 constantly recalculating a route seems to apply to the 340 as well. It's almost as if it detects being off-route (even if it isn't) and so recalculates the route. It does rather make me feel that perhaps I should bought a Tom Tom Rider.

Well I can't answer for how the 340 behaves as I've never used one ... but both my nuvis that can use routes don't exhibit the behaviour you described from Calais to Tours, it may therefore either be a problem with the route you sent to the 340 or the 340 itself.

Incidentally I see the 340 uses trip planner. When you open the trip planner app on your Zumo are you selecting the first or last place in the trip? If you want it to follow the route you've planned on Basecamp you need to select the first point, not the last. Are you doing that?

That's interesting, I remember seeing that but I have no idea what I did. I'll bear it in mind the next time I use it.

Thanks!
