Your Garmin GPS unit should indicate that it is connected to your computer when plugged into a USB port. The location and size of the connector may vary between units, but it can generally be found along the side or back of the GPS. On some devices like the Garmin nüvi 2200, the connector for the computer USB cable is the same port as that used by the car charger. Others like the nüvi 2300 have two USB connectors, a micro-USB port, and a mini-USB port. Each GPS will vary, so be sure to compare GPS features to see what tools, accessories, and add-ons are available for your system.
Garmin nüvi models and others will usually have an icon appear on the screen when connected to the computer by USB cable, showing an illustration depicting a connected computer and device. This indicates that the device is in USB mass storage mode. Because there are no obvious signs that the unit is charging, many users will now wonder if their GPS is actually charging.
To prevent the GPS from automatically entering USB storage mode and displaying the computer icon on its screen, users can "eject" the nüvi device from their computer to allow it to charge while off. In most cases, however, the GPS should charge automatically whether on or off.
There are a few simple steps to follow to ensure that your GPS charges when plugged into your computer USB port. The following directions are specific to the Garmin nüvi 250 model, but should apply to similar units. This guide will walk you through the basics of how to charge a Garmin GPS on a PC:
- Turn off your Garmin GPS and plug the device into your computer with your USB cable. Your computer should automatically detect the GPS.
- Open your "Computer" folder to view your drives and devices with removable storage. The Garmin logo GPS icon should appear here.
- Hold the power switch to the "on" position on your GPS. On your computer, right-click on the GPS icon and select "Eject" to remove the device. On a Mac, the Garmin icon can be dragged to the trash can. The computer image on your GPS screen should now disappear.
- Let go of the power switch and the GPS unit will indicate that it is switching to battery power supply.
