My tom tom displays a red cros through memory card whe switching it on.I have tried reseting it and inserted card into pc but even pc wont read it.The pc shows there are used space on card but wont let me read it .

Try reseting it:<br /><br /> Use a straightened paper clip, or something similar, to push the reset button for 15 seconds. The reset button is on the bottom<br /><br />(support.tomtom.com)<br />

This means it is not reading the SD card and that it needs to be re-formatted.

This is best done in a card reader and not the tomtom itself.
Right click on it and select format select FAT32 as the files system

Now 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

It should now work

danaged card or blank

This problem is due to the memory card not containing the TomTom application or map. To update the application onto the memory card, Connect the device to your computer. Open the TomTom Home application. Click on 'Update My Device'. This should then install the application onto the SD card. Alternativly, you could perform all the steps above without the SD card in the device, this will install the application onto the internal memory. Note: you may also need to install your maps, voices, etc after you update.

I saved the map on to my computer from the tom tom in Tom Tom Home and installed it on to a new SD card and now it working perfectly. I bought a 2mb SD card for £6.70 put it into a card reader and connected to computer and installed map and it gave me the instructions to put into device (Tom Tom) and switch on to connect then off and back into card reader to finish. Then I disconnected device which is important to do by the way put the new Sd card into Tom Tom and it is workink perfectly. I hope this help others who have problems.

What I can suggest is download the drivers & software first .. Than buy another brand of memory card.. I had same issue with a Mp3 player that I had purchased.. It wouldnt recognise the card even though it was setup properly.. I returned it and baught a different brand.. Worked Like a Charm..

#2 If you for some reason cant get the software to install or work properly, I suggest you buy a new Tom Tom (( EXACT MODEL )) and than take the old Tom Tom put it in the new box and take it back with your receipt and tell them this doesnt work.. Ive done that b4 with a Speaker system and it wasnt an issue with the store...

Good Luck !

You need to reset it, by holding in the reset button for 15 seconds. If there is an SD card or memory card of any kind, take this out first. sometimes you have to use something sharp like a paper clip, and push it into a small reset 'hole' in the back of the unit.
then put the memory card back in. then look online for step-by -step instructions, usually from the vendor, on how to update the software, if indeed it is at all necessary. Also, try doing the update on a PC instead, there's a chance it's not supported for Macs. I know this is controversial.. i hate Windows too.. :)

hopefully the reset button will resurrect yr tomtom though.
good luck

check fire wall setting if u have a back up for ur security soft remove it from the computer and try disabling all startup items
then check

I had the same issue after installing updates, I contacted tomtom & they talked me through it.

I think i had to wipe the card & through my tomtom home software they reformated the card & go it sorted.
