Determining if an Automotive Device is Fully Charged
It is recommended to always have the device plugged in when being used. The device will charge while it is plugged in, but the only way to determine if it is fully charged is to have it unplugged and on the main menu as seen below. The battery icon will be displayed in the top right corner of the screen.
To check the device's expected battery life, visit the product page on the Garmin website and select the Specs tab.
