Updating the Software on Your eTrex Touch 35 or 35t

Software for your Garmin outdoor handheld should be kept up-to-date in order to take advantage of improvements and bug fixes. Updates are free and easy to install. When updating your outdoor handheld for the first time, we recommend using the Garmin Express™ program on a computer. Subsequent software updates can be done wirelessly when the handheld is connected with the Garmin Connect™ app via Bluetooth.

Garmin Express requires the use of a computer running Windows or Mac and checks for software updates automatically each time you connect your Garmin device to the computer.

Updating Software Through Garmin Express

If this is your first time using a computer with your outdoor handheld, you will need to download and install Garmin Express. For more details, see - How Do I Install Garmin Express Software?

  1. Connect your outdoor handheld to your computer with the appropriate USB cable.

  2. Launch Garmin Express.

  3. Select your Garmin device.

  4. Garmin Express will then display the available updates. Select Install or Install All.

    • Review and accept any prompts for Terms and Conditions or Important Notes.

  5. Once complete, disconnect your outdoor handheld from the computer.

Updating Software Through the Garmin Connect App

The Garmin Connect app is primarily for tracking fitness goals, but it also allows for software updates to be transferred to a paired Garmin device via Bluetooth. If software updates are available they will be downloaded and synced to the handheld automatically behind the scenes. Once the available updates have been downloaded, it may take up to 48 hours for the handheld to prompt you to install the update.

No additional steps need to be done apart from setting up Bluetooth on the handheld, nor are there any steps that can be used to expedite these types of automatic updates. If you wish to install software updates immediately, Garmin Express must be used.

For steps on pairing with the Garmin Connect app, see - Pairing a Smartphone with Your Device.
