Garmin automotive device displays the message "No Detailed Maps Found"
What should I do if my Garmin automotive device displays the message "No Detailed Maps Found That Support Routing" or "No Map Data Available?"
This message generally displays when there is something wrong with the mapping files on the device. There are multiple fixes. First ensure that maps are enabled on your Garmin device, by going to Setting>Map & Vehicle>myMaps. In myMaps check the box next to the map you wish to load. If the error persists, then reinstall the maps, and update your device again. If the error occurred after installing a new SD card, the card itself may not be formatted correctly. Format and reinstall the SD card if this is the case, this should correct the error.
Did everything by the book. Formatted the USB drive per guideline from Garmin, got the GarminDevice.xml from the car and able to download the update from Garmin using the newly installed most current release of Garmin Express. I was able to install the update to my car and received a successful message of the installation. But when I tried to use the Where To Address function to specify the destination address, I received a message “Data Map for this vehicle is not available”. I double checked through Settings/Map & Vehicle/myMaps and all maps for North America were already checked. I then went back to Garmin Express to Reinstall the update and after going through the same process as before, the problem remains. I checked the file folders on the USB drive and it appears the download process was successful. Any suggestions?
