Zumo XT route calculation error across country border

I have a Zumo XT running version 6.5, connected to my Windows computer running Basecamp, version 4.7.5, using the City Navigator 2024 map, and I am getting a route calculation error when attempting a route that crosses from USA into Canada.  I have tried this using two waypoints only to make it as simple as possible, but the error continues.  Please see the attached image.  The only way I could get around it was to split my route by country.  As long as the route was wholly within either country the route would create correctly.  Something that has recently updated has changed to cause this condition as it was working correctly just 3 months prior.

If there is a fix for this or some change I can make to prevent this I would like to know.

Thank you,

  • It would be nice if BaseCamp opened a pop-up to explain the issue.

    I doubt that the closure times are fubar.  It is more likely that BaseCamp ignores them.

    I think in MapSource and possibly earlier versions of BaseCamp the user could set a start date/time and seasonal closures would be applied.

    The issues are that opening and closure dates probably won't fall on exactly the same day every year.  Just because a route is created in the summer doesn't mean that a user won't try to use it in February.

    It seems to me that current devices always recalculate routes when activated.  It might be interesting to send a route intended to go over the pass to your device (without a specified start date)  and see what happens.  I'm sure others would be interested in your findings.

  • I will try to send it to my GPS unit for sure, but I'd like to be able to plan a route in basecamp without wondering if the route is optimal or not. In this case, it's clearly not, but it could be more subtle.

    For information, the latest version of Basecamp still allows you to define a start date for your journey and in my case, the date is set in summer, so shouldn't be affected by closure time:

  • Well that will depend on what data is in the map, certainly sounds like there are some errors.
