Lost my tomtom one SD card

tomtom HOME

Theres good news for you, you can get a SD card for your tomtom, and all you have to do is to install or download your maps on the SD card then fix it into your tomtom and you will be able to view your maps from there. For the lost maps, connect your tomtom to your computer, be sure to have your drivers software, then you select your tomtom form your computer, then you install all lost maps back on it by restoring all old maps. But for large downloads, download all new maps on a SD card. That should do the job.
Hope this information came in handy.

Dicky smith stires sell TOMTOM and should be able to direct you to gettiong the maps reset on the card. The uniques ID is essential but if you still have proof of purchase you may get out of having to buy a new licence. Lost of peoplke have bought GPS off Ebay and then claimed faulty card and approached TOMTOM for replacement maps. They have wised up to the scammers now and want proof of purchase or else you pay again. But see what DSE says about the matter

You can not use a sd card from one TomTom and put it into another TomTom. The operating system on the card is coded for each individual TomTom device. First try doing a reset with the card installed on your dads TomTom. The reset hole is on the bottom of the TomTom marked reset Use a streightened paper clip, insert the paper clip into the hole until you feel a click then hold it in for 20 seconds. If that didn't work and you have a card reader insert your dads sd card into the reader and make a backup of the everything on the sd card. Just copy and paste everything on the card to a folder on the desktop you have created on your desktop. Next delete everything on the sd card EXCEPT the maps and ttgo.bif or ttgo.bak file. Now that you have made a backup and deleted everything on the sd card except for the maps and ttgo.bif or ttgo.bak open TomTom Home. TomTom Home should see your card and install the operating system back onto the sd card. If it doesn't you may have to insert the sd card back into your dads TomTom and connect it to the pc. It may take a few times of doing this to get the latest operating system back onto your dads TomTom. You can do the same for your TomTom, but you cannot use any thing bigger than a 2 gb sd card. Do not get sdhc cards they won't work. This will only put the operating system for your TomTom onto the sd card. When you have installed the operating system onto your device it will say "no maps found", you will have to buy the map from TomTom..

I do some work with TomTom - it's possible that if something interrupted or went wrong during the install, the map could have been deleted. TomTom is aware of the problem and is working to fix it - if you are map-less, call support (866 486 6866) and we can work on getting you a new map.

Hi, Here's a link where you can buy another SD card. Good luck. If this helps plz rate this 'fixa'. If you need more help leave a comment, I'll be happy to help. Thank you kindly.

I am very sorry to hear that you had no backup. Theres no way you can recover data once you have deleted it from an sd card. BUT , If you still have the authorisation card ( thats the one that generates the activation code ) then you might be able to copy data from another tomtom card to your card then reactivate it with the authorisation card. GOOD LUCK.

OTHER TOMTOM USERS NOTE: Backup your SD Card.

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

You could probably just manually delete the Canada/USA maps from the device, and copy over the europe (or whichever ones you need) to the device. 
Just plug it in, and view the memory like a normal usb drive..delete the old, copy over the new.
Don't forget to use tomtom home to backup your gps device to your computer first (thus saving your canada maps for later..)
Afterwards, you would probably have to go into your preferences and choose the europe maps.
Good luck!
