Updating your garmin gps
Manufacturers offer updates for these maps on their individual company websites.
There is other software available for varying formats, some specific and some open for all systems to use.
Click the "install" button once it's available during the installation process.
Follow the on-screen prompts to complete the installation process.
While a GPS unit makes finding a destination much easier on the road, outdated maps and software make the device less effective.
Keep your Garmin GPS unit up to date through the company's Garmin Express application for Mac or Windows computers.
Choose the "select all" option to install all available software and map updates.
Connect your Garmin GPS unit to a Windows or Mac computer using the USB cable that came with the GPS device, or use any mini or micro USB cable that fits the device. Garmin makes GPS updates a lot easier to handle by offering one application to manage every type of portable automotive Garmin GPS unit.
Download the Garmin Express app for free from the Garmin website, selecting either the Windows or Mac version.
The updates may take several hours to install; check the on-screen time estimate to get an idea how long the process may take.
Wait until the app shows "installation complete" before closing Garmin Express.
