Excited to see new roads and route information after you get Garmin GPS updates?

Well, everyone feels the same curiosity. All this excitement flushes off when your device refuses to turn on or work after you get an update.

Garmin device not working after update is common trouble that users do encounter seldom. Once you are done with installing new Garmin map on the device, you need to disconnect and restart it. Your device reboots appropriately, but then you get to see an error "Can't authenticate map" on your screen.

This may happen because the update files get corrupted, either during downloading or while saving on our SD card.

You are stuck now; your device won't work until you clear of this error. Following are a few simple troubleshooting steps that will help you to make this error go away.

The best way is to get a new Garmin map download from Map install. That means to start the map update downloading process again.

  • A new download will get you all required files, i.e., .img, .gma, .uni in the correct format again.
  • Delete the previously saved map update files from system folder in the device and paste these new files on your system.
    TIP: In case you are unable to locate these files on your device. You should open Windows Explorer> folder options and select the "Display all hidden files and folders" option.
  • Once you delete the old Gmap files; you need to restart your device again. Now, you will not see any authentication error. Moreover, your Garmin GPS device will work fine with the newly installed map updates.

One thing you should take care of is; do not eject your device immediately from the system. Once you get the success message for download complete wait a little more afterward. It takes a short time to get the updates to settle on your device.

Disconnecting GPS immediately from computer may interrupt this process, and your files may get corrupt. Still, need help with Garmin device not working after the update?
