Help ive accidently wiped everything off my sd card ive a tomtom 300 go is there anything i can do

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..

reformat your micro sd card,"by right clicking the micro card in my computer, you can format it" this wipes the card clean and download the latest software from R4 and then reinstall everything, hopes this helps

Hi,
You might have the switch on SD card set to "read only" , This would stop your tomtom being able to write to the SD card ... hence , " unable to store settings " message . .... OR ... the folder where your tomtom wants to store the settings is corrupted ( on your SD card ) so it can't store them.... or similarly , the file is corrupted on the SD card ( maybe the card is damaged ) so the existing file cannot be overwritten . Check out all these possibilities before suspecting any hardware fault on your tomtom ..... GOOD LUCK

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.

Hi,

Unfortunatly if you have deleted everything and do not have any backup then you will not be able to restore your TomTom to working condition.

If you do manage to copy or obtain SD card with files / maps then you will need the origonal product code and activation numbers in order to activate the maps. TomTom home software might restore some of the files needed but you will still need Maps and activation for the TomTom to work.

best regards and Good Luck

The downloaded maps can be copied direct to the SD card or copied to the SD card via USB lead and PC connected through TomTom Home. Once you have the map on your SD card you will need to activate it with your product code number that you obtained when you purchased the map.

Good luck

before you start take out sd card. 1 turn tomtom upside down. 2 see reset button? 3 use paper clip to press (press for 15secs) 4 now turn on tomtom (hold power button for approx 5secs. 5 re insert sd card. after a few minutes you should have signal. hope this solves your problem.

Hi Albert. Theres lots of data on the card besides the map that your tomtom needs in order for it to work. Theres really no solution can be offered as unfortunatly something has happened to the data on your card and something is either missing or corrupted. Exactly what would need to be investigated and its not really within the scope of doing so on this forum. Without any judgement to you or anyone else can I warn all other tomtom users ..... BACK UP YOUR SD CARD TO YOUR COMPUTER before you attempt any "update" to your tomtom. If you have made a backup Albert then I suggest you reload the backup onto your card and everything should work again. Fingers crossed. You might need to do a hard reset by pressing the reset button underneath your tomtom with a paper clip through the reset hole. Good luck.
