The Nuvi 255W is part of Garmin's affordable line of GPS devices.Despite its relatively lower price compared to the company's high-end models, the 255W still manages to include important features such as voice navigation, picture viewing and a built-in battery for portable use.Well now that we know we can take advantage of free maps for our satnav, what are the steps we should take to get them?It will open a new tab where you can download Garmin Express , a little app that will deal with your Satnav’s updates.After copying the maps you will receive a confirmation message from the Garmin Express program: button we can see the storage memory and how much of it has been taken by the new maps as well as the available space.A GPS device is only as good as its maps, so you want to make sure that you have the newest, most accurate map data available before you hit the road.In addition, Garmin continually updates the device's operating software in order to refine your user experience.However, if you wish to take advantage of these device upgrades, you must download and install the software updates through Garmin's Web Updater program.

If you have recently purchased a Garmin Nuvi with LMT or LM extension (for example Garmin Nuvi 1450 LM, Nuvi 1300 LM, Nuvi 2595lmt, etc) it means that you can benefit from free lifetime map updates (the life of the device of course, or better yet the average usage duration of a Garmin Nuvi).

The download process of the maps may take 2-3 hours depending on your Internet speed, the availability of the server and the size of the downloaded files.

After the new maps are fully downloaded, they will be copied in the memory of the Garmin Nuvi GPS device, which will take approximately 10-15 minutes.

It also offers points of interest, live traffic updates, lane assistance and many other features.

To keep your maps accurate and the device's software running smoothly, you'll need to perform an occasional update.
