Do you want to change the language of the VOICE or the WORDS IN THE SCREEN? These two are independent from each other and need to be set up by separate.

1) To change the VOICE, you need to download an ENGLISH VOICE.
a) Start TomTom Home on your computer.
b) Plug in the TomTom dock to a USB port on your computer and plug in your TomTom GPS on the dock
c) Turn on the GPS and when asked "connect to computer" answer "yes" (you may not be asked if you want to connect; TomTom Home amy detect your GPS and connect to it automatically). If your GPS is not connecting to TomTom Home, turn the GPS off, turn it upside down and press the "reset" button for 7 seconds, place the GPS back on the dock and turn it on. It should automatically connect to TomTom Home now.
d) On the TomTom Home software, click on the icon labeled "Add Traffic, Voice, cameras..."
e) Click on the icon labeled "voices"
f) Click on the icon labeled "computer voices"
g) Click on any of the voices that says "English" on the second ("language") column; download and install the voice
h) Go to the TomTom Home top menu and under "DEVICE" choose "DISCONNECT DEVICE". Wait a few seconds until the GPS communication with the computer is broken and the GPS restarts. You don't need the computer anymore for now
i) On your TomTOm GPS, tap on the middle of the screen to bring the menu.
j) Touch "CHANGE PREFERENCES"
k) Touch "VOICE PREFERENCES"
l) Touch "CHANGE VOICE"
m) Select any of the voices that are in English (such as "SUSAN, English US, Computer"). After this, you can TEST the voice. Check that you can hear the voice, otherwise, you'll need to adjust the volume. We'll do this later. Touch "SELECT" to select the voice. Press "DONE" on the next 3 screens until you're back to the GPS navigation screen
n) To change the volume, tap on the LOWER LEFT rectangle. You'll get a VOLUME SLIDE. Slide it to the RIGHT to increase the volume and to the LEFT to lower it. I keep mine around 85% volume. YOU ARE DONE SETTING UP A NEW VOICE

2) To change the LANGUAGE of the WRITTEN DIRECTIONS on the screen:
a) On your TomTom GPS screen, tap on the middle of the screen to bring the MAIN MENU on
b) Tap on the PREFERENCES icon
c) Tap on the RIGHT ARROW 7 times or until you see an icon labeled "CHANGE LANGUAGE".
d) Using the UO and DOWN arrows on the GPS screen, scroll up or down untill you see the langauges you're looking for. You'll get a screen with several languages available, including "English UK" and "English US"
d) Touch on the screen you want. The screen will automatically go back to the previous menu screen that shows the "CHANGE LANGUAGE" icon. Touch the "DONE" button.

YOU ARE ALL DONE. Now, your VOICE and all WRITTEN DIRECTIONS should be in ENGLISH.

I found this article online, and it may work for you:

"Ok this has worked on at least four tomtom one’s
And one xl’s that i have tried,
First of all connect your tomtom to your computer.
making sure your online,Go to log on.
if you’ve not created an account create one now.
If you’ve had to create an account restart tomtom home.


You should have the tomtom home screen in front of you,
Now even if tomtom home is showing you logged in, ignore
this click your email adderss in the top right hand side of the screen
and log in again and click continue.
Then click Device/disconnect device.
Now your tomtom will update itself and your maps will be restored"

1) Has the GPS been dropped or gotten wet?
2) Did the TomTom get physically disconnected before issuing the "disconnect device" from the TomTom Home drop down menu? (this can corrupt the software inside the GPS)
3) Try reinstalling TomTom Home from www.tomtom.com in your computer

Another thing to try:

Tap the satellite bars in the lower right corner. This will bring you to a screen called "Status summary." You'll see satellite bars on the right-hand side of the screen. Tap them.

This will bring you to GPS Status. Tap "Configure" in the lower left corner. Change the coordinate display to D.D (or if it's on D.D right now, change it to DM.M). Tap "Done" then "Done" again.

Has that fixed the problem?

Sounds like the LCD has some dead pixels on it. There is no cure for dead pixels other than replacing the LCD screen.

you may need to download the latest GPSfix updates. This can be done via the tomtom home software
