It is important to let this procedure complete - don't be tempted to switch on/off your device even if it looks like nothing is happening.The software update procedure can take several minutes to complete so be patient. It is advisable not to update your sat-nav if the battery is flat, make sure it is charged. Your sat-nav may not have sufficient space for the map update.

If all goes to plan, not only will the latest maps for your sat-nav be installed but also the latest device software, Bluetooth updates, voice updates and so on. Register your sat-nav by entering your email address when requested to do so. I recommend that you only use Express if you have a good and reliable broadband connection as some of the maps files are very large and take several hours to download from Garmin. During the update procedure and depending on your device, you may be asked to disconnent your sat-nav from your PC and reboot it (turning it back on).

At the end of the process your sat-nav will be right up to date. This step is the installation of the latest software (not the maps) for your device.

In this case you update the maps on your sat-nav using Garmin Express which you download from Garmin's website and install on your PC or Mac.

Once downloaded and installed, the update process is relatively straightforward.

You have an option to purchase either a one-time map update which currently costs €59 or lifetime map updates which costs €89.

If your sat-nav is over 3 years old, I would recommend the onetime update only.

I also explained how to update Nuvi gps systems with Lifetime Maps in this tutorial .

At OSM maps are free, created and updated by users and volunteers across the words.

Even with several years of updating various models of Garmin sat-navs, I have found the experience torturous at times.

You buy a micro/SD card preloaded with the Ireland/UK maps, you insert it into the side of your device and off you go.

Often (but not always), at three years the battery in the sat-navs start to deteriorate and as the lifetime map updates are not transferable to a new device, sometimes it can be more cost effective to replace the sat-nav with a new device rather than update it.
