Custom Route is Changed on Device to Follow Road
When a device is loaded with autorouting maps such as the City Navigator NT or select TOPO maps, a custom route loaded to the device may deviate from the intended course and follow the road instead. Because portable devices and current handheld devices have autorouting capabilities, they calculate routes in accordance to the map and Routing Activity selected.
If the custom route keeps changing to a route on a road on the map, Direct Routing will need to be selected for the Routing Activity instead of what is currently selected. Only in Direct Routing mode will a device ignore the roads and paths shown in an autorouting map and follow the custom created route.
To change the routing preference on these devices, follow these general steps:
From the main menu, select Setup.
Select Routing.
Select Direct Routing, or select Activity > Direct Routing.
If needed, refer to your device's owner's manual for more specific instructions.
