3790LMT

 

Does anyone know why my 3790LMT will not recognize my SanDisk 8gb micro SDHC memory card?

Welcome to the factory

Have you tried reformatting the SD card? Use FAT32. Is the SD card recognized by a computer or other device? It's possible the card needs to have its contacts cleaned or that it's defective. Do you have any other SD cards you can try to confirm that the problem is with the card and not with the nuvi?

When you say the nuvi doesn't recognize the card, what do you mean by this? If you're putting files on the SD card and want the nuvi to use them, tell us the type of files you're using and what folder on the SD card they're in.

There is a Getting Started button in the upper right of this page right under POI Files. It is worthwhile visiting this page.

To make navigation easy, most browsers provide the following option. When you want to follow a link - but still keep your current page open - you can hold down the "Ctrl" key as you left-click on a link. That action will open a new "Tab" in your browser up on the "Tab" bar. When you then left-click on that new "Tab", you will follow the link - leaving the "Tab" you are now reading open and available to click on and return here.

So, using the "Getting Started" link, you might try the "Ctrl" - left-click sequence and then return here. You can return by either "X-ing" out of the "Getting Started" page (using the "X" on the "Tab" itself) or just left-clicking on the "Tab" for the page you are on right now.

Since you are new here, I encourage you to go through a couple of the Beginner Education FAQs.

The first link makes sure the settings on your computer are such that you can do more advanced POI loading.

The next link helps you make a backup of your GPS by attaching it to your computer. (NEVER do anything to your GPS until you have a backup)

Is your nuvi in MTP or MS mode?
