Charging a zūmo® 660 or zūmo® 665 GPS navigator

Garmin recommends always using the power cable packaged with your device or a Garmin-branded AC power charger. Full power will ensure that your device gets the best signals from GPS satellites and traffic updates.

Third-party cables or adapters may not charge the device or put it in the proper state to receive updates.

There are Two Ways to Charge the Internal Battery in Your Automotive Device:

Use the vehicle power cable that came with your device. A full charge may take up to 6 hours. All devices come with power cables to charge the device. You may use either the automotive or motorcycle power cable. This is the Garmin recommended method for charging your device.

Use an AC power adapter accessory, such as a wall power adapter. A full charge via an 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. Use the port directly on the device when charging indoors. A compatible AC adapter can be purchased from Garmin's online store.

Temperature can affect the charging of a device. The battery won't charge if it registers a temperature of 0°C (32°F) and below or 45°C (113°F) and above. See Charging Factors for an Automotive Device for more information about the effects of temperature on your device.

The battery will not drain when an automotive device is connected to external power.

See How Can I Tell Whether My Automotive Device is Charging? to ensure your device is charging properly.

A Garmin AC adapter or replacement cable can be purchased at Garmin’s online store.
