Duplicate routes and waypoints on device

Former Member over 9 years ago

I have just bought a Nuvi 2559LMT and am using it with Basecamp 4.4.7

My problem is that every time I send My Collection to the device, it duplicates both the routes and the waypoints on the device. Also if the same waypoint is used in more than one route, then that waypoint also is duplicated. In some cases I have ended up with the same waypoint 6 times as a result of having a route ending in a place where another route starts and where I have updated the device more than once.

The obvious workaround is to delete everything from the device before updating it from Basecamp but that gets pretty annoying after a while.

Anyone had this problem and found a better solution?

It’s not worth doing a special test. I’ve only owned outdoor handhelds – most with very limited memory back when I used MapSource. I often opened two or more images of MapSource to accomplish some tasks (copy and pastes between the multiple running applications).

If I recall correctly, MapSource checked most but not all data fields for a Waypoint object to see if an incoming Waypoint was the same as an existing one. However, the only options were to replace the existing object or cancel the paste. The example I provided would not be too uncommon for people who share data where simple names tend to be used often. I was just curious if MapSource behaved the same way in transfers to devices as it does for transfers between multiple images of the application.

The more I read about the Nuvi line, the more alien it seems to be from the outdoor handheld devices. I’m afraid I would run into an “old dog/new tricks” issue if I got one. But most of my uses are off road, so I'm not really sure of my need for a dedicated driving device.

Thanks for your reply.

I am a real newbie with my Nuvi 2789 (about a month) or any automotive GPS since I have only owned handhelds before. However, I live & die by created routes (usually with shaping points) in either Map Source or Base Camp so the ability to transfer data into my Nuvi was critical to the buying decision.

I have tons of data stored and organized in Base Camp and typically load waypoints and/or routes before embarking to a place I feel I need the GPS to get to, the same process I use with my trusty GPSMAP 60CSx

In my initial attempts to load data into the Nuvi from Base Camp I had the same problem regarding duplicate waypoints. What I discovered was, the duplication happened when I loaded waypoints AND routes (using those same waypoints) into my Nuvi from Base Camp. So what I do now is, NOT load ANY waypoints into the unit that are part of a route.

When I just load the routes, I also get the waypoints that are part of that route in my Nuvi, without the annoying duplication problem.

Unfortunately a similar issue rears it's ugly head if I create a return route that has shaping points.

One of the things I have a hard time dealing with when using the Nuvi 2789 is the lack of a "invert route" option in the unit like I am familiar with in my GPSMAP 60CSx. So I typically create a return route in Map Source by duplicating an existing route and invert it in Map Source. Unfortunately, if the route I duplicate has any shaping points, they get duplicated too.

Base Camp does ask you if you want to duplicate waypoints when duplicating a route which I always say NO to, but that doesn't apply to shaping points. My work around for that is after duplicating the route in Base Camp, I copy the original shaping points from the original route and paste them into the inverted route, delete the duplicated shaping points and recalculate the route.

The end result is a to and from route with no duplicate waypoints or shaping points. If I load JUST the routes into the Nuvi and not any waypoints that are part of a route...

...all is well.

Hope this might help someone with the same problem.
