You can get a Garmin free map update after registering your Garmin device at their website. Like I have registered the one after purchasing Nuvi 255w and I got a free update. To load maps on your Garmin Nuvi start with –
- Go to MapSource.
- Click on the tools menu.
- Select a region for your map.
- Click on transfer menu.
- Click send to device.
- Click on send before completing the download.
You can also seek help from Garmin website to have more info on Garmin free map updates.
