SOURCE: Nuvi 350 System Software Missing

Try this: Hold the power buuton down, you will see on the lower screen the word "Pre Booting - ". Keep holding the power button for about 60 second, then you will see on the lower screen "Booting".
This time, release power button; system will reboot and loading map... again.
I got the same problem, after research on the web. Nick 99990_0 had post this solution on (his Nuvi 660) but it work for my Nuvi 350 too. Good luck.

SOURCE: Windows XP will not recognize Garmin 200W

I had the same issue. I would plug it in and it would recognize the device then it would disappear.

What I did to solve the problem was to first turn on my Gamin 200w. After it was finished loading maps then I plugged in in to the usb port. My machine recognized the device without any problems. I am running Windows Vista Home Premium. Hope that helps.

Guys and or ladies... I know that you have to create a folder named "GARMIN" in the sd card so the maps can be recognize. Maybe this solves your problem. Let me know if it works.

How to update your Garmin Satnav maps


To update your garmin satnav map you must have your satnav registered. If it's already registered skip to paragraph 2 below.

1. To Register your Garmin Satnav
  • Connecty our satnav to your computer and go to www.garmin.com
  • Select your country
  • Click on Register your garmin product
  • Follow the prompts
Note you will be asked to create a username and password. Write them down and keep them safe as you'll need them again anytime you want to update your maps

2. To update your maps

  • Connect your satnav to your computer and go to www.garmin.com
  • Click on myGarmin and log in
  • Click on myMaps.
  • If there's an update available it will be shown beside the name of your map.
  • Click on Get Update and follow the prompts.
Note map files are large so you'll need a broadband connection to download them. If you don't have broadband you'll have an option to buy the update on DVD.

  1. If The Map Is Too Large To Install To Your Satnav
    When you go to download the map by default it tries to download it to the satnav i.e. not the SD/Mini SD card. You need to change this. When the website recognises the satnav follow the prompts. It will give you 3 options for the download destination.
    • Download to satnav,
    • Download to Computer and Satnav or
    • Download to computer.
    As the website is updated, from time to time, the method of selecting the download destination changes. Sometimes it shows up as a drop box with a drop-down arrow showing your satnav name. Click the drop-down arrow and select the option to download the map to your computer. Sometimes it shows the 3 options as text headings with tick boxes beside them and you get to tick the option you want. Whichever way it shows up select the option to download the map to your computer. This will install it on your computer's hard drive.

  2. After it's downloaded the map should begin to install automatically. (If not double click on it and it will). It should be allowed to install to your satnav first as Garmin will not allow it to install to your SD/Mini SD card unless it's first partly installed to the satnav. This is so they can ensure that it's installed to the correct satnav.

  3. To Install The Full Map To Your SD/Mini SD Card
    To install the map to your SD/Mini SD card, insert the card into the card slot of your satnav and connect it to the computer. Click the windows start button on your computer. Then click the GARMIN progam and then MAPINSTALL. This runs the map installation program. When the install program finds your satnav and you get the option to install the map there again by default. Click on the drop-down arrow, where it shows your satnav as the destination, and select the drive letter of the SD/Mini SD card. This will be different to the drive letter for your satnav. The map will then be installed to your SD/Mini SD card.


  4. Problems With Older Nuvi Satnavs Reading Maps On 4 Gb Or Higher SD Cards
    When you install a map to an SD card older nuvi satnavs can have difficulty getting the satnav to read it. It will install to it without problem but when you try to operate the satnav then it cannot load the map and will close down the satnav unless you remove the SD card. The reason for this is that 4 Gb and higher cards are SDHC which operate differently from SD. To solve this problem you should use a class 2 SDHC card, which is the slowest type available. You can identify the class by the small figure on the card. It will be either 2, 4, 6, 8, or 10. Before you install the map format the card as described below. Also use webinstaller to check that you have the latest version of operating software on your satnav.

  5. Format the SD card with "Panasonic SD Formatter" available from http://panasonic.jp/support/global/cs/sd/download/sd_formatter20.html rather than the standard windows format function. Select the fast format option and be sure you have selected the drive letter of your SDHC card as it will format your hard drive or indeed your satnav just as easily if you select one of them by mistake.

  6. To update your software or check that you have the latest version, you can download webupdater from http://www8.garmin.com/support/collection.jsp?product=999-99999-27
    Connect your satnav to the computer and run the program. It will search for any updates to your software.
Class 2 SDHC cards are harder to find in shops today as they are being replaced by the faster classes. They are however still easily available on ebay if you can't find one in the shops.

Garmin Nuvi 755t Stuck in power up cycle


You can do two things.

First, plug the GPS in overnight in a regular USB charger. If the battery charges up, then the problem is with your Garmin vehicle cable.

If it does not charge up, you can buy a battery replacement kit for it: https://www.amazon.com/Garmin-Nuvi-755-Replacement-Installation/dp/B003VFSR4M

Garmin nuvi 1390t won't read or recognize microsd


The 1390t works with microSD cards. Your 8GB card is actually a microSDHC card. While it fits into the slot, it will not work in older devices.
You need to go with microSD cards, 2GB and smaller.

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.

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 am trying to download the Mexico 2011 map and the download stops because it states I do not have enough space. They advised a 4 GB SD chip which I purchased and installed. The download still stops and it...


When you go to download the map by default it tries to download it to the satnav i.e. not the SD card. When the website recognises the satnav it shows it in a drop box with a drop-down arrow. Click the drop-down arrow and it should give you the option to download the map to your computer. Download it to the hard drive.

After it's downloaded it may begin the install automatically. If not click the START button on your computer and go to GARMIN. In the garmin menu click MAPINSTALL to begin the installation.

When the install program finds your satnav and you get the option to install the map there again click on the drop-down arrow and select the drive letter of the SD card. This will be different to the drive letter for your satnav. The map will then be installed to your SD card.

Before you begin to install to the SD card you should know that it can be very hard to get get the 200W, and other satnavs of the same age, to run the map from SD cards. It will install to it without problem but when you try to operate the satnav then it cannot load the map and will close down again unless you remove the SD card. I recently had this problem with a garmin nuvi 760 and contacted garmin about it. They told me the problem is that 4 Gb SD cards are SDHC which operate differently from SD. They said to get a class 2 SDHC card. (You can identify the class by the small figure on the card. It will be either 2, 4, 6, 8, or 10). Before you install the map format the card. Also use webinstaller to check that you have the latest version of operating software on your satnav.

Format the SD card with "Panasonic SD Formatter" available from http://panasonic.jp/support/global/cs/sd/download/sd_formatter20.html
rather than the standard windows format function. Select the fast format option and be sure you have selected the drive letter of your SDHC card as it will format your hard drive just as easily if you select it by accident or your satnav.

To update your software you can download webupdater from http://www8.garmin.com/support/collection.jsp?product=999-99999-27
Connect your satnav to the computer and run the program. It will search for any updates to your software.
Class 2 SDHC cards are available on ebay if you can't find one in the shops.
After failing to get mine to work on a class 4 SDHC 4Gb card I followed their instructions and it worked for me. Hope it works for you too.

How do I load itunes songs to Garmin Nuvi 755T?


Songs in iTunes are in the AAC format. The Garmin only recognizes MP3s. You would have to convert the files before you could transfer them.
