Trying to connect tomtom 910 to PC & device won't recognise in usb. no connection signal, message or anything. before this just updated tomtom home to latest version. could this be compatabilty issue? tried plugging device thru usb on 2nd computer & usb just doesn't recognise, even as an external drive. Thanks

I have a TomTom Go 910 and I had the same problem. I thought the problem was with the GO 910 but it turned out to be with the computer instead. The GO 910 seems to corrupt the USB driver files on the computer over a period of time when you connect it to your computer to update it or for whatever reason you connect to your computer. To repair the USB driver files on the computer, right click on My Computer and in the menu that opens up select Manage. In the Computer Management window that opens up select Device Manager from the left side of the Computer management window. Then in the right lower side of the window (you might have to scroll down) you will see Universal Serial Bus Controllers. Click the + sign to expand the Bus Controllers. Start at the bottom of the longer lines that you see and right click on it. In the selection that opens up left click on uninstall. Starting from first of the longest lines at the bottom, uninstall all of the USB drivers. Sometimes they will reinstall themselves before you can get them all uninstalled, but if you keep at it you will be able to get them all uninstalled and then restart your computer. When the computer restarts you will see messages that the computer has found new hardware. Then after the computer is on for a few minutes you will see messages that your new hardware is installed and ready to use. If the USB driver files were corrupted this will reinstall them with the correct drivers and you can connect your TomTom to Update it or for whatever reason. Also when you do this make sure that you don't have any USB devices connected to your computer until you are done, then you can connect your TomTom.

Always make sure you get regular updates from your tomtom home software that should be on your computer, this will help you to connect to sats

Try doing a device update while connected to tomtom home, if that doesnt work backup your device onto your commputer and try reinstalling the software and maps ect onto your device.

Hopefully all you need to do is a soft reset. To do this use a streightened paper clip and insert it into the small round hole marked reset on the bottom of your tt. Gently press the reset button in until you feel a click. Hold the reset button in for 20 seconds. Hope this does the job.

You need the TomTom Home software that comes on the cd with it to connect to computer using a usb cable.

Go to TOMTOM website and reinstall driver. If that doesn't work, try a different USB port.

Complain to Tom Tom ,you may have a lemon,look for law suit soon

1 Have you got Tom Tom home installed on your PC?
2 Have you got Tom Tom in the home 'cradle' with the usb lead attached?

I have both and have no proba at all

Had a similar problem with my GO 930, i.e. it would not connect to the PC. As several people have suggested, it appears to be a problem with the docking station connection. I found, by trial and error, that this works for my system (so far, every time):

Remove GO from docking station.
Switch on and allow to boot up.
Place FIRMLY in docking station
The Go should now recognise that it is linked to a PC and will ask if you wish to connect.
Proceed as normal.

As mentioned, my sytem is a 930, so this may not work for 910s.

try this it does take a while to do.
STEP 1

Connect your TomTom to your computer via USB and open up your Windows Explorer and go to the drive. (It will be listed as TOMTOM (E) or some other drive letter).

Copy the Yellow Folders one by one to your PC. Ideally, save all the folders under a new folder that you name.

You may find that the folder ttntools and gns may not be copied. This is o.k. if they aren't.

STEP 2

Format your Tomtom via MY Computer.

STEP 3

Copy the Yellow Folders from the backup you made in STEP 1 back to the TomTom.

STEP 4

Open TomTom Home
Click on Upate Now.
Install the latest update onto your TomTom.
Once installed, switch your TomTom off, then disconnect if from the PC.

Thats it. From now on, make a full backup using TomTom Home prior to any updates.

Also note, that copying all the files will take some time.
