Garmin nuvi 255w map update

Mon Aug 24, 2020 6:58 pm

Hi all,
I have an older Garmin Nuvi 255W satnav unit that I want to do some map updates. Unfortunately, this unit does not have Lifetime map updates. This has been confirmed with Garmin Express. The installed map is from 2011.
How can I manually update this unit with updated newer maps? Also, I want to install the new maps on a 32GB microsd card.
Any help would be greatly appreciated.

Put your chosen Unlocked maps(renamed) into a Garmin folder on the FAT32 formatted SD card as below

<Path>Garmin</Path>
<BaseName>gmapsupp</BaseName>
<FileExtension>img</FileExtension>
<Path>Garmin</Path>
<BaseName>gmapsup1</BaseName>
