My 945 will not turn on or charge. What should I do?

If your Garmin device won't turn on or charge, there are some basic troubleshooting steps that you can perform.

Is the Device Possibly Locked up?

In some instances, a device can appear locked up or frozen and not respond to any input including pressing a key, swiping the screen (touchscreen devices), or plugging the device into external power. You can attempt to recover the device by performing the following steps if your device has a physical power button:

NOTE: Following these steps may result in a loss of some data such as recent steps taken (activity trackers) or a loss of current time. To correct the time, sync the device with a smartphone using the Garmin Connect app or a personal computer using Garmin Express. For GPS devices go outside and acquire a GPS signal.

  1. Plug the device into an external power source using the power/data cable.

  2. Press and hold the power button until the screen changes (hold up to 30 seconds).

Is the Charging Cable in Working Condition?

Confirm that the cable is not damaged which would prevent the device from charging. Check the charging pins to ensure they are free of debris and not damaged. Replace the cable if necessary.

Are the Charging Contact Points on the Device in Working Condition?

Check the charging contact points on the device for damage, dirt, or debris. Use a pencil eraser or a cotton swab dipped in rubbing alcohol to clean them.

Is the Battery on the Device Fully Charged?

Plug the device into a power source using the power/data cable.

How do I load music from a streaming service to my Forerunner 945/945 LTE?

Music content from some streaming services can be loaded to a Forerunner 945 or 945 LTE by installing an available Connect IQ music app to the watch.

Select an option below for detailed instructions to install and sync music to your watch:

How do I Set Up Which Notifications Display on My Forerunner 945/945 LTE?

Controlling which notifications you see on your Garmin device is managed from your phone. Steps differ between Apple and Android.


Notifications are managed from the iOS notification setting on the phone.

  1. From the iPone select Settings.
  2. Select Notifications.
  3. From the top of the screen, make sure Show Previews is set to Always or When Unlocked. This is a setting required by Apple to display notifications on a Bluetooth paired device.
  4. A little farther down the screen, under NOTIFICATION STYLE, select the app you want to configure (e.g., Messages, Mail, etc.).
  • To SEE NOTIFICATIONS for a specific app on your Garmin device:
    • Allow Notifications should be toggled on.
    • Under ALERTS, make sure there is a check mark under Notification Center.
    • At the bottom, under OPTIONS or LOCK SCREEN APPEARANCE, you must have Show Previews set to either Always or When Unlocked. This is a setting required by Apple to display notifications on a Bluetooth paired device.
  • To DISABLE NOTIFICATIONS from displaying on your Garmin device:
    • Choose the app you want to control from the NOTIFICATIONS SETTINGS screen.
    • Under ALERTS, uncheck Notification Center. This will also result in notifications no longer appearing in the phone's notifications no longer appearing in the phone's notification center.

Repeat step 4 for each individual app to either allow or disable notifications from the app.


Controlling what notifications display on your Garmin device can be managed from the Garmin Connect app.

  1. Open the Garmin Connect app on your phone.
  2. Select menu bars (top left).
  3. Select Settings.
  4. Select Notifications.
  5. Select App Notifications.

From here, toggle to enable or disable all smart notifications or customize by selecting individual apps.
