Basecamp dropping via points when transfering

Former Member over 9 years ago

This has been a consistent problem. I create a route in BaseCamp and it has say 42 via points. I transfer it to my 660 or my husband's 550 Zumo and the route will usually drop 7-10 points. But each device will not necessarily drop the same number of points.

I imported a 62 point route from The New England Riders webpage. When I opened it in BaseCamp it had 53 points. I transferred it to my 660 Zumo and it had 42 points. A friend had the same route on his 660. We put his SD card in my 660 and imported his 62 point route into my 660. It was fine, 62 points. I've checked all my BaseCamp settings and there's nothing obvious that might be causing this.

All software is up to date.

Ideas?

Basecamp's method of string search sorting of waypoint names is alpha-numerical and can give unexpected route point Deletions/Omissions. In addition, BC may delete (thin) inline waypoints on a routed road vector if it deems those points to be redundant.

I only tried importing a single 15 Stop route file from Delorme Topo/Street Atlas in gpx format before seeing this happen and gave up on the process. This was a year or two ago.

However my experience with generic gpx route file import directly into a Garmin Nuvi 56 Trip Planner App, using much more complicated and detailed routing points (Stops/Vias/Shape Points/Locations), is that the Nuvi can handle the import parsing quite well, and may sort names differently from BC.

YMMV Your mileage will vary.

MotoNancy,

It sounds like your copy of BaseCamp is mangling the files somehow or they are being mangled when they are downloaded. What operating system and operating system version are you running? What version of BaseCamp?

What happens if you download that 62 Waypoint file from New England Riders and transfer it to your 660 without using BaseCamp?

What happens if you import it into BaseCamp and then export it to your desktop and then use your normal windows file manager to transfer it to your 660?

If you are adept with computers you might try downloading and installing a text editor with an xml mode to it and compare the gpx files from your friend, as downloaded by you, and as exported from BaseCamp to see if there are any differences. I think Notepad++ and the XML Tools plugin might work.

Or, post links to the files here and let us look at them
