MY tomtom go 720 was working fine. Now, when I power it on, I get a picture of the tomtom unit on a green and white background, and then nothing else will happen. I cannot connect it to my computer. I have tried resetting with a paper clip, and this hasn't helped. Any ideas?

Re: Tomtom go 720 won't start up
Leave on charge for two hours, then if you have a sd card take 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.

I had the same problem. I tried uninstalling software and re-installing it. That did not help. I reset my TomTom Go 720 with the reset button on the bottom of the unit. The computer then recognized my TomTom.
hook it to your usb cable to your for a few hours and then try and start it. first with the power button, it that fails try the hard reset..if neither those work, download tomtom home. follow the directions and tomtom home should be able to repair it unless you have internal problems, like a bad usb port on the gps. bill
This happens with my cell phone all the time too, just have to go to manage phones and delete my phone then re-configure it and that seems to fix it for a while at least. Also night & day always has to be done manually, it won't change automatically that i'm aware of. I'm pretty sure i had to download some of the free voices from the TomTom Home or website initially, in any case i prefer to use my TomTom 720 without voice as becomes annoying listening all day nag nag nag blah blah blah.
First turn your firewall off (if you have one). You need to go into
your 720 with the TomTom Home software and erase the downloaded
software (with the remove items from my device) and reset the device
(little reset button under the unit keep it pressed for 5 seconds),
place it back in the cradle and restart your computer and than restart
the 720 , bring the TomTom Home program up, and when the TomTom Home
software in your computer restarts and detects the 720 it will tell you
that you need to update the application, if it doesn't than you force
the update by going to the add maps option, select items on my
computer, select applications and press the add button, when done, go
back and to device (option in top of your screen) and select disconnect
device, restart your 720 and it should be back to life with the
1. Connect the TomTom to the USB for power (green light should be on).
2. Hit the reset button on the bottom of the device - you should feel it depress slightly.
3. Press firmly and hold the power button and count to 10.
5. Try this a couple of times if it doesn't work the first time.
Even if your battery is ****, the power connection has a pass-through, so you can still use the device as long as its connected to the charger.
