    Hi, thanks for that info but I want to have it on a sd card and not put it directly on my gps. It shows up that it is installed on the sd card but for some reason when I put the sd card in the gps it does not show up on the gps unit.

I have never tried this way. I always use the Transfer function (send to device) from my map source. Either the SD card is too small or that procedure is not proper. Just use the Transfer function.

    I am speculating that when the computer copied the map into the SD card, it uses a different format from when the map source transfers it using the send to device function. In other words, you cannot read the map from the SD card built that way.

I want to delete maps from my Garmin Nuvi 1450 LMT to make room for different country maps. How would I do this? I have been looking for answers online and in manual for hours now with no luck. Please...


    • 1 Remove the SD card from the Garmin GPS.
    • 2 Insert SD card into your computer's card reader.
    • 3 Open the "My Computer" in either the desktop or the start button.
    • 4 Double click the SD card folder to open it.
    • 5 Hold "Ctrl" on your keyboard and left click on all the map files in the folder. Once they are all highlighted, right click and select "Copy."
    • 6 Go to your desktop, right click and select "Paste." You have created backup copies of the maps in your Garmin GPS. Return to the SD card folder via "My Computer."
    • 7 Select the map file you wish to delete, left click it once and press both "Shift" and "Delete" on your keyboard.
    • 8 Return the SD card into Garmin GPS. Turn it on. Check the screen to see if the right map has been deleted. If any mistakes are made, simply start over from step 1. Replace any map that has been accidentally deleted.

    • OR Insert one end of the USB cable into the USB port on the Garmin. Insert the other end of the cable into the USB port on the computer.
    • 2 Click on the desktop "Start" menu, and chose the "Computer" folder.
  1. 3 Right-click on the Garmin drive folder, and select "Open." Some Garmin GPS devices (e.g., Nuvi 200 through 800 series devices) will have the map files stored here. Browse this folder for maps you want to remove, right-click on the file and select "Delete." If no map files are available, go to step 4.


  • 4 Double-click to open the "Map" folder.
  • 5 Right-click on any map file that you want to remove, and select "Delete."

    I bought a lifetime update from Garmin a few years ago but now my nuvi 270 tells me that I don't have enough memory to install the latest maps and that I must choose only certain regions. I have an 8Gb...


    The internal memory of the nuvi is full. Some maps will need to be delete before any new maps can be added. Typically, the map in the nuvi is named GMAPPROM.IMG and a map installed to an SD (or SDHC) memory card is named GMAPSUPP.IMG.

    1) Remove the SD card from the memory slot

    2) Connect the nuvi to the computer via USB cable.

    3) Open the nuvi drive.

    4) Locate and delete the GMAPPROM.IMG (or GSUPPROM.IMG) file(s). Optionally copy (instead of deleting) them to your hard drive in case there is a problem wit the new map file(s).

    5) Empty the Recycle Bin.

    6) Retry the map update of the nuvi.

    This method will take some time to perform depending on how many map segments you are sending to the nuvi. Transferring the entire map can take over an hour. A quicker way is to send the maps to the SDHC card directly by inserting the card into a card reader. This eleminates the slow Garmin card reader from the equation and transfers are done in a fraction of the time. No maps will be on the nuvi - they will all be on the memory card instead. To update the SD or SDHC card, do this:

    1) Repeat steps 1 thru 5 above. This removes the maps files from the nuvi.

    2) Disconnect the nuvi from the computer.

    3) Connect a card reader to the computer.

    4) Insert the SD or SDHC card into the reader.

    5) Locate and delete the GMAPPROM.IMG (or GSUPPROM.IMG) file(s). Optionally copy (instead of deleting) them to your hard drive in case there is a problem wit the new map file(s).

    6) Update the map to the SD or SDHC card.

    When either method is employed, only one map file set will result. GMAPPROM.IMG or GMAPSUPP.IMG is the name of this file set. You should ensure / change the name to GMAPPROM.IMG. Any subsequent file set added should be named GMAPSUPP.IMG.

    I hope this helps & good luck! Please rate my reply - thanks.

    You need to download the map to your compute rather than the SD card. When downloading the default destination is the satnav but you can change it to your computer. When it's installed to your computer you then click the windows START button and in the list of programs you'll find a GARMIN folder with a program called MAPINSTALL. Connect the satnav to your computer with the SD card in. Run MAPINSTALL and select the SD card as the destination.

    You can get more details of how to do it at http://www.fixya.com/support/r5628920-update_garmin_satnav_maps
    Note maps installed to SD cards do not always work with Garmin Nuvis. To give it every chance of success please follow the instructions at the above link about formatting the SD card.

    How instal maps on sd memori card for garmin nuvi 250


    Hello

    Insert the memory card into the memory card slot on Garmin Nuvi 250 GPS device. The memory card slot is located on the left side of the device. Push the card in until it clicks. (If you inserted a memory card that already has pre-installed maps and files, there is no further action required. The device will access the new maps based on the address you enter.)


    Connect the Garmin GPS to the computer using the USB cable. The mini-USB connector will need to be inserted into the rear of the Nuvi 250; the larger end is inserted into the computer's USB port.


    Locate the computer file that you want to download to the Garmin memory card. The Nuvi 250 is capable of reading JPEG formatted images and GPX formatted Waypoints and other mapping-related files. Right-click on it. Select "Copy."


    Select the "Computer" folder from the computer's desktop Start menu. Double-click on the "Removable Disk" drive that represents the Garmin Nuvi.


    Right-click in an empty space within the drive and select "Paste." The files have now downloaded to the memory card and will be accessible through the Nuvi 250 menu options.


    Good Luck, and do rate the solution if got help

    I purchase the lifetime updates for my Nuvi 200W GPS and now it will not allow me to download any updates on to it due to not enough memory. What can I do. I am pretty upset because I spent the money for...


    Unfortunately the garmin 200W, like most of the garmin satnavs, doesn't have much storage space so you should be given the option to download part of the map only to your satnav. To get the full map the only option is to download the map to your computer. When you go to download the map from the garmin website select OPTIONS. In the options menu select download to computer. This installs a program called Mapinstall on your computer which contains the map. If you need to use more of the map you can then either replace the part installed on your satnav by running the mapinstall program from your computer or install it to an SD card. Note however that while garmin say that nuvi satnavs support SD cards up to 16 Gb some cards don't seem to work in them. Before spending all the time it takes to put your map on the card test it in your satnav first by putting music or pictures on it to see if it works

    Sd/garmin


    By connecting your garmin to your computer via USB, the sd card you have loaded in it will turn up as removable storage on your computer. You can treat it like a hardrive.

    Without a cable, you can remove the sd card from the garmin and place it in a card reader hooked up to your computer.
