What is the requirement sd card to download tom tom navigator

you need a flash adapter card and then tom tom fixtures and settings

If you don't have maps, you can't navigate.

So: Get an SD card. Download the maps.

Question for you: How did you wind up with a navigator with no card and no maps? You might consider taking it back to the place you bought it and exchange it for one with the minimum necessary to make it work.

Remove the SD card

The card needs to be formatted properly first that's all,

formatting is better done in a card reader.

Right click on it and select format select FAT32 as the files system

Update your device without the SD card.

Make sure your GPS runs OK without the SD card

Now re-connect the tomtom but don't let tomtom home run. exit TTH if need be.

You now ned to select your tom tom which will also show as a drive.

In windows explorer select tools then folder options.

Click view and tick the box for "show hidden files and folders"
It may warn you but you can ignore it.

then just copy ALL the files from the tom tom to your sd card

DO NOT USE CUT AND PASTE !

Once all the files are on switch off the tom tom and insert the sd card and re-boot
It should now work again

If you backed up your tom tom then restore it from that backup. Two maps should not stop you from getting to the tom tom home web but may stop the home application working properly.

If you have an SD card in remove it and try again if all is good then try put the sd card in a reader rather than the tom tom and make the required deletions from there. Or if you DO have a backup then format the card properly and then restore to it whilst it is in the reader. Then put it back in the tom-tom and you should then be back to where you need

My best suggestion is to contact the manufacturer so that you can get the proper software for your gps system.

more than likely, I just purchased a new tomtom sd card on ebay with all the new maps on it, ver.7 got it for a UK seller no problems, did you back it up on your computer? hopfully you did, then you can just connect it to tomtom home and reinstall it.

If you have TomTom that have the slot for SD card, then it should accepted the SD card. The instruction for how to use the SD card is simple, but it is hidden in the TomTom Home, that's why it's difficult to find it. Below are the instruction how to use the SD card.

1. Format the SD card (FAT32) and do not stick the SD in the slot yet
2. Run Backup (connect TomTom device to computer)
3. Disconnect TomTom from computer and turn off
4. Slide the SD into the slot and connect TomTom back to computer (choose "yes")
5. In the TomTom Home menu, Choosen Backup & Restore >>> and choosen Restore

TomTom Home will add all applications to the SD card. So the internal memory still have the applications and the SD card also had the same applications. Everytime you slide the card in, TomTom will automatic detect and use it as its primary storage, if it not detect, you can go to the device menu and pick the device to connect to.
Whenver you take the SD card out, then TomTom will use its internal memory.

Hope this helpful

I don't think the Tomtom 910 has a SD card slot. Check the model # of your GPS again.
