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
I had a similar error and I fixed it. That is, as far as I know...
Here's my theory: The SD card is acting like it has an error on it. This often happens when it is removed improperly.
HERE'S HOW TO FIX IT:
Remove your SD card from your GPS
Insert your SD card into an SD card reader or connect it to your PC
Wait for windows to go through it's process of discovering your the "removable storage device" your just connected (see step 2)
(This step may be different depending on what version of Windows you are using or depending on how you have your OS laid out). Look at the lower right hand corner of your desktop. There should me a small icon there with a green circle and a check mark. It looks like this...
Click that with the right mouse button.
It will say "Safely Remove Hardware" - Left click that message.
A window will pop up allowing you to select your SD card and "Safely Remove" it (it will have a letter name like "drive F" for example).
Wait for the windows to tell you it is ok to remove your hardware - then remove your SD card form the PC
Make sure your GPS is turned off.
Insert the SD card into your GPS.
Turn on your GPS
That's all! I hope I was able to help.

Its more than likely that the data on your SD card has become corrupt or the card itself has become damaged / faulty. This can cause the tomtom to feeze on startup and doesn't even get past the loading process. You can "half" prove this by turning the tomtom ON without the SD card inserted. If you get the startup drums then a ' please insert SD card ' symbol on the screen , The card IS FAULTY . good luck. .................Hopefully , you backed up your SD card to your PC some time ago. If this is the case , you can just reload the files onto your SD card.
You definitely need software and maps on an SD card. The TOMTOM will not work without a card inserted. The card will contain MAPS , Map authorisation codes ( to show they are genuine TOMTOM maps bought and paid for ) , POI ( points of interest ), GPS fix data , voices ( for spoken navigation ) etc etc etc. ....................
PLEASE NOTE , TRYING A CARD FROM ANOTHER TOMTOM is very unlikely to work. Each card has an authorisation code that is generated via an algorithm inside each TOMTOM and is device specific.
However , trying a card from another tomtom might produce a diferrent result but still not work , at least this might prove that the tomtom is working OK before you rush out and buy a tomtom card.
"My tom tom wonts switch on. I have reset it and still it comes on with a boom boom noise and shows the 2 hands on the screen. It also shows the loading bar at the bottom, but then it just freezes and nothing happens. can anyone help please ASAP"
Sound as though your Map data card is corrupt. Remove the SD card and check it with your computer using a card reader. Backup the SD card onto your computer. You can run either chkdsk or go to the drive letter under 'My Computer' right click and select properties, then tools, then check now. You can also try starting the Tomtom with the SD card out of the unit. It should show a picture of the Tomtom with a 'X'. You can also try copying the data on the SD card to another SD card.
Reset the unit by pushing a bent paperclip or pin into the hole on the bottom marked 'reset' turn it back on, plug it in & charge it via USB overnight or as long as you can in the car, make sure the led on the top is green, tap the bottom right of the screen & check the battery symbol on the unit says charging underneath.
If this doesn't help.
