The message "The imported route(s) were calculated with different maps. Would you like to recalculate the route(s)?" may appear on a device capable of multiple-stop routing.

This message should only appear when a route was created in a mapping program (e.g., BaseCamp) then transferred to a device using a different mapping version than what was used in the program.

First, check which mapping version is installed to the device.

To See Which Map Version is Installed:

Open the device's Settings menu
Touch Navigation
Touch Map & Vehicle
Touch myMaps

Then, when using BaseCamp (Windows), a drop-down menu will appear near the top of the window whenever more than one mapping product is installed to the computer.

To Confirm the Installed Map When Using BaseCamp:

Open BaseCamp
Click Maps
Select the relevant map set

Once the route has been created with the same mapping version, the message will no longer appear.
