Charging an Automotive Device

Garmin recommends that you always operate your automotive device with it connected to a power source. Full power will ensure that your device gets the best signals from GPS satellites and traffic updates.

It is advised to always use a vehicle power cable or Garmin-branded AC power charger. Third-party cables or adapters may not charge the device or put it in the proper state to receive updates. The message "Attached power cable cannot charge device. Use the cable provided with your device" may display on the device if using a third-party cable or adapter.

There are two ways to charge your automotive device's internal battery:

Note: The device will not charge when plugged into a USB cable while plugged into a USB port in the vehicle or through the computer.

Use the vehicle power cable that came with your device. A full charge may take 3 to 4 hours The device will charge while powered-on, as well as when the device is powered off and plugged into a running vehicle All devices come with power cables to charge the device. You may use either the automotive or motorcycle power cable This is the recommended method for charging your device.

Use a Garmin-branded AC power adapter accessory, such as a wall power adapter. A full charge via a Garmin-branded AC power adapter may take 3 to 4 hours When you plug the device into an AC charger and push the button to turn it “off”, the device will remain on enough to charge the battery, then fully suspend or turn off It is recommended that you use the port directly on the device when charging indoors Third-party AC adapters may not be able to charge the device. A Garmin-compatible AC adapter can be purchased from Garmin's online store

Temperature can affect the charging of a device. If the battery registers a temperature of 0°C (32°F) and below or 45°C (113°F) and above, it will not charge. For more information about the effects of temperature on your device, see Related Content.

When an automotive device is connected to external power, it will be operating from that external power. The battery will not drain.

If you need a Garmin-branded AC adapter or a replacement cable,  they can be purchased at Garmin’s online store.
