There may be a problem with the mapping files if the message “No Detailed Maps Found That Support Routing” is displayed after turning on an automotive device. The message “No Map Data Available” may display when searching for a destination. This may cause the device to show only the locations of major cities or major highways with no side streets.

Note: A "Cannot calculate the route" error message will appear when routing to an area if maps are disabled.

To Correct This Problem:

Ensure the Garmin Express™ software is up to date and reinstall the maps.
- See Garmin Express not Working for Updates and Downloads if the install does not complete.
- For the zūmo® XT and zūmo® XT2 GPS navigators, see the Manage Maps steps below if Garmin Express does not display a Reinstall Map option for the missing map.
For “No Detailed Maps Found That Support Routing” - if it cannot be dismissed by pressing OK or the back button, press and hold your finger on the message to clear it.
- If the device displays "Can't Unlock Maps" after clearing the message, follow the instructions in Correcting the Message "Can't Unlock Maps" or "Can't Authenticate Maps" on a Garmin Automotive Device.
