Re: tom tom go 910
TOM Tom no charge and will not turn on leave on charge for two hours, then with the SD card out hold down the reset button at the back of unit for ten seconds and then the 'on' switch for ten seconds. 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.
Format your Tomtom via MY Computer.
Copy the Yellow Folders from the backup
you made in STEP 1 back to the TomTom.
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.

My thanks to the gentleman who posted the link to Tom Tom's solutions link. Although I had been there previously months ago when I first encountered this problem, there had been at that time, no instructions from them on how to properly reset the One that does not have a reset pin hole. That was in March. There are now such instructions.
The key to resetting such a Tom Tom GPS device lies in plugging your One into your computer, which automatically launches Tom Tom Home software (please remember, you have to have Home software installed on your computer already). After doing this:
1. When Home launches, go to Manage My Device Folder (p.2) and click it to open it.
2. You will see a folder-style window which lists all of the items that are your device. Select the folder tab: 'Items on device.' Then Deselect Applications. Click OK when promted. The Applications software will be deleted from your Tom Tom One.
3. IMPORTANT! Then clcik the other folder tab 'Items on computer.' Do the same here by deselcting to uninstal software on your computer as well. Click OK when promted.
4. If you do not get an automatic dialog box indicating that you need new application software installed, return to p.1 and select the folder 'Update My Device.' Follow the instructions as prompted and Tom Tom will both download new computer Home software as well as new software to the One device.
That should do it.
I will tell you that it took me three passes at this process. So it's not a breeze. But in the end it finally worked. And my One, which had been down since March is once again finally up and running with new software and as well as I remember it working.
Hope this helps others.
try to reset the unit. There is a small hole on the bottom of the unit, insert a small pin on the hole and hold it for a couple of seconds and it will reset it, you might loose the addresses saved so you might want to copy them before resetting it.
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
The red cross means its been wiped usually. Connect it to your pc and go to my computer. Click on the tom tom logo and see what is on your device. The maps should be there in yellow folders. Copy and paste these in to a folder. Then reformat the device by right clicking on the logo and selecting fat 32. When done reset the device for 30 sec and connect back to your pc and install the latest version of tom tom home. You can then get all the fee updates, thhen go to add maps where you can put your maps back on from the folder you made
