What do I do if my device doesn't support the SD card feature during the Garmin Express map update?

In situations where a Garmin device does not have sufficient internal memory to load full coverage of a City Navigator NT map update, Garmin Express allows the maps to be installed to a removable SD / MicroSD card. Most devices support this feature, but there are some exceptions:

  • Nissan 700
  • nuvi 295
  • nuvi 300/500/600/800/805 series
  • nuvi 5000
  • zumo 450/550/665
  • GPSMAP 640
  • Aviation devices

These devices do not support this feature. Garmin Express will automatically offer to install a smaller coverage region to these devices when there is not enough internal memory to install full coverage. Coverage regions may be changed as often as desired. To install a different coverage area, see How do I reinstall maps or change coverage using Garmin Express?

If full coverage is needed on one of these devices, a workaround exists to install the maps to an SD / MicroSD card.

To install a map update to a memory card using this workaround, the map update must first be installed to the computer.

If the update has not been installed to the device yet:

  1. Open Garmin Express
  2. Select the device to update
  3. Click on View Details
  4. Click on Installation Options
  5. Select Computer and Device
  6. Click on Install or Install All
  7. Accept the license agreement
  8. Click Continue
  9. Select a region to install to the device, then click Continue

If the update has already been installed to the device previously:

  1. Open Garmin Express
  2. Select the device to update
  3. Click on Map Options
  4. Click on Install to Computer
  5. Accept the license agreement
  6. Click Install Update

After the installation is complete, maps can be installed to the memory card using Garmin MapInstall. To do this, follow the instructions in the article How do I install maps to my device with MapInstall?

Once the desired maps are installed to the memory card, they will function the same as maps installed to the internal memory.
