To keep your Honda Navigation System up to date, purchase an update DVD through the navigation page of Honda.com and load it into your system. Honda releases map updates annually, as of 2015.
Visit Honda.com, and click Menu. On the drop menu, click Honda Autos under the Our Brands heading. On the Honda Autos page, click Owners. Place the cursor over Vehicle Information, and click Subscriptions, Downloads & Updates on the drop menu that appears. Go to the Updates section of the page and click Get Navigation Updates.
On the navigation page, click a vehicle. On the drop menu, select a vehicle year. The site brings up the map CD for that vehicle, but you are also able to double-check by looking for the vehicle under Compatibility. Click Add to Cart to purchase the DVD.
After you add the item to your cart, the site takes you to your cart page, which displays your estimated order price. Click Checkout. Enter your shipping and billing information to complete the checkout process.
Once you have the DVD, open the vehicle's touch screen to reveal the DVD slot. Remove the DVD that's already there and put the update DVD in its place. The vehicle downloads the DVD software. When it complete the download, the system restarts and the maps are updated.
