Garmin GPS Maps

[pablocat]

Hi,

I am wondering if anyone knows how to manually transfer updated maps from a newer Garmin GPS unit that has lifetime map updates, to an older Garmin GPS unit that requires you to purchase the maps.

Any help would be appreciated.

To be honest I don’t see maps changing that much, how many new roads have been built in past 6 years. 

Anyhow give this site a try:

Maybe if you could be precise with what you want to update. What model of Garmin is it ? (portable, android version of Garmin, embarked in a car,...)

Make a precise description of what you want may eventually give you a better answer than letting anybody guess in the wild.

Hi Bad Karma,

Thanks for replying.

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 on this unit is from 2011.

What I want to do is manually update this unit with updated  newer North America maps? Also, I want to install the new maps on a 32GB microsd card

Any help would be greatly appreciated.

Download United States map for 32GB sd card

This site uses BitTorrent for map downloads. If you don't already have a BitTorrent application installed, I recommend installing: µTorrent.

Click on - download map for sd card.

You have download magnet link:
OpenMapChest_Contiguous_United_States_2020.08.22_gmapsupp.torrent

Click on it and µTorrent will start downloading the map:
OpenMapChest_Contiguous_United_States_2020.08.22.zip

Installing the Map on an SD-card

1. Unzip the zip file that you have downloaded.
2. You will have a file called "gmapsupp.img".
3. Insert your SD-card into your SD-card reader. 
4. If you don't have an SD-card reader, you can connect your Garmin GPS to your computer with a USB cable. Make sure that the SD-card is in the GPS unit before you plug it into the computer.

You need to format SD-card with FAT32

How do I format my SD card to fat32:

1. Connect the 32GB sd card to your computer.
2. Right-click the SD card and choose Format.
3. Select FAT32 as the file system.
4. Apply the changes.

Copy the Map on an SD-card

1. Open the SD-card with the file manager. 
2. Create a new folder and name the folder "Garmin", the folder name must begin with a capital "G"
3. Copy the "gmapsupp.img" file into the "Garmin folder" on the SD-card. 
4. Safely remove the SD-card once the file has finished copying

Turn on your Garmin GPS with the SD-card inserted and go through the following screen navigation:

1. Touch the Map Info button at the bottom and check the box beside the OpenMapChest map to enable it.
2. You should also uncheck the built-in map if the map areas overlap.

Should work but if not try:

Not many, for sure my , uk666.

However, it happens more and more that in 1 and the same year some cities change their streets, from double sided to one-way streets.

That's the main reason why I update my maps every time new ones are released.

Also for the POI's. Lot's of Cams are added the latest updates
