How to Upgrade an Old Garmin

- 2). Click the "Update Maps" option under the "Maps" tab.
- 3). Click on the type of device you would like to update. If you are updating the maps on your mobile phone, click "Phones." GPS devices for your car are found under "All Other Devices."
- 4). Install the "Garmin Communicator Plugin" if you don't already have it on your computer.
- 5). Connect the USB cable that came with your Garmin device to your computer once the installation process is complete. This lets you upload any updated maps onto your Garmin device. Once plugged in, the updates will occur automatically.
