Tutorial: Installing Downloadable Maps to Garmin's BaseCamp Software and your GPS

Below you will find several guides to install your map. First is a quick guide for those with advanced computer use or those that just need a quick reminder. Second is a video that walks you through the installation step-by-step (see note below for video viewing). Finally, we have a very detailed step-by-step written tutorial with screen captures (pictures). If you follow these instructions closely we will walk you through each step of the process and show you exactly what to do on your computer.

It is important to note that you can use any of Garmin's Map Management Softwares (Trip and Waypoint Managers) to view the maps and transfer to a GPS unit - BaseCamp or MapSource. These programs are very similar, so the steps taken to install the maps are the same until the final step of Transferring the Maps to your GPS. BaseCamp is highly recommended because it is newer software, updated frequently, and is easier to install.

To unlock your purchased copy of your map you'll need the unique Unit ID of your GPS receiver. The Unit ID is a 10-digit number which is absolutely unique. Every Garmin GPS receiver has such a number.

Watch this video if you need help getting your Unit ID or read the written instructions below the video.

  1. There are two ways to find your Unit ID:
    1. In BaseCamp, simply connect your GPS to your computer and turn it on to view your GPS's model and Unit ID on the left side of the screen under 'Devices'.

    2. Image showing a device's Unit ID in Garmin BaseCamp

    3. To get the Unit ID only with the help of your GPS, turn it on and go to the 'Main Menu' > 'Setup' > 'System' and then press or select the menu button. Choose Software Version. Please write down the Unit ID. You will need it later. (For newer GPS units [Oregon, Dakota, Nuvi, & Colorado series], go to 'Setup' > 'About')
  2. After you have your GPS unit ID please log into the MyMaps web page using your Email Address and Password which were sent to you with your order confirmation. After logging in, go to your My Maps page and select the 'Generate Unlock Code' button.

Part 4 - Uploading the map to your Garmin GPS (BaseCamp users)

  1. Open your BaseCamp program. With your GPS connected and turned on, BaseCamp will recognize your GPS unit and display it's information in the left hand part of your screen under 'Devices'. If you have an SD/microSD memory card in your GPS, this will also be displayed under 'Devices' as 'Removable Media' (Unless you have an eTrex, Rino, or GPSMAP series GPS)
  2. You can transfer maps to either your GPS's internal memory or to the external memory card (Removable Media). We will generally transfer maps to the external memory chip because of limitations on the internal memory of the GPS (see your GPS unit's specifications to find out how much internal memory your GPS has) [NOTE: Your Removable Disk may not be shown if you have an eTrex, Rino, or GPSMAP series GPS - this is normal - see the note in the next step]
  3. To transfer mapsets to the 'Removable Disk' (MicroSD card) you will need to right click on 'Removable Disk' or it's 'All Data' Folder under 'Devices' on the lefthand side of the screen. [NOTE: Your Removable Disk may not be shown if you have an eTrex, Rino, or GPSMAP series GPS - right click on your GPS unit's name, select 'Install Maps' and the maps will be sent to the Removable Disk]

  9. In this window you can see all maps that can be installed on your GPS. To install the whole map, simply select the check box. Be sure to monitor the storage bar to make sure you have enough memory on your GPS. If your GPS doesn't have enough memory, you may have to use the Advanced/Partial Install button in the bottom left to select a smaller area of the map to install or clear some data from your device. Once you have selected all the maps you want to send to your GPS, press 'Continue'
