You hopefully will receive an email with a link to a zip file. Visit the website, choose the Garmin OSM map type, give your map a name, choose the area, provide an email address and select ‘extract’. It is important before you continue, that you charge the device as you wouldn’t want to have a battery issue during the update. If you’re running a version of software earlier than 7.80, you probably should update the device. All I know for certain is that the software version I used with the 255W is 7.80, as shown in the screenshot below.Īlso the software version is shown on the device. I wasn’t around for this step, but my friend might have updated the sat nav device to the latest version using the Garmin Express software.

However I used an sd card reader instead and saved some battery life!

If you turn off the 255W, insert an sd card and then connect the sat nav to a computer (such as a machine running Windows 10) via a USB cable, you can access the card’s memory. NOTE: This how to guide has been written as much for me, as to help others! So it is aimed specifically at the 255W device, as well as having one map on a card and replacing the map on the internal memory. I just used the new map that I placed on the internal memory. If you don’t want to use a SD card, you won’t want to use all the instructions below, but please don’t forget to backup the device and make sure it is fully charged.ģrd Warning: I wasn’t in a position to test whether the map on the sd card worked, but it shows as being listed.

I think you should reconsider and use the sd card method. Warning: You are not to hold me or anyone else responsible for any problems you incur, including costs from reading this blog post, following instructions on this site or from downloading any files.Ģnd Warning: You might want to just replace the map on the internal memory, and not use a sd card. What follows is how I installed these maps on the device. My friend went out for a short trip in the UK and used the device without any issues. I made sure both maps were selected via the settings. I found an excellent site that provides free maps.įor the 255W I was able to replace the map on the internal memory, then have a second map on an SD card. This blog post is about how to install free maps on a Garmin Nüvi 255W Sat Nav.Ī friend purchased an old sat nav via eBay and asked me to replace its 2010 UK map with a more recent map, as well as install a free map for Australia.
