Well, did you try to hold that PIN for 10 sec?
If doesn't help, then update your NavCore ;)

Tomtom 700 dead

After checking around around the web it seems that you are not the only one to get the green screen of death. My suggestion is to hold reset for several seconds, release reset and hold the power button button for 10 seconds. If this doesn't work the only other option is to let the unit sit for several days to let the internal battery completly drain, once drained theirs a good chance it will function normally, this allows any temporary memory to be cleared. Good Luck & hope this helps L8R

Bought a TomTom 340s want to reset to factory settings b4 returning it, maps seem hopeless in Canada

1. Switch on the GPS 2. Tap on the screen 3. Tap on Change preferences 4. tap on the arrow 5 times (If you look on the top left hand corner you will see Preferences 6 of 6 at this point.) 5. tap on reset factory settings.
However, I find it very unfortunate that you had difficulty wit this GPS because I use the same unit in Canada and I find it way better than the Megallan I had. Did you try to update to the latest map. If not give that a try using TomTom home. It may be a good idea to check the Planning preferences screen (This option is on Preferences 4 of 6). Try changing one or two options on planning preferences and check whether the GPS behaves better.

Cannot use tomtom

Hello dungtaff,

Fom what you describe it sound like you might have a faulty cigarette lighter lead. This may have caused higher voltage that normal to be input to the TomTom. If possible have the lead checked for its voltage output as it should be around 5v . Unfortunatly , if the lead has put too much voltas into your TomTom then it will have damaged it inside usually causing 1 or more IC's to blow. The repair will not be possible at home DIY style as it requires special soldering techniques and tools as the parts are extremely small. A seach on the internet or maybe ebay will give you some repair people.

The first problem you had might not be the same problem as this time . For resetting the TomTom you only need to do a single momentary push of the button ( not too hard as the reset button is delicate ) . This does a quick disconnect of the battery causing reset of proccessors. You might also try another type of reset where you hold the ON button whilst again doing a momentary push of the rest button. Ideally you should then have the TomTom on charge when you first attempt to switch it on after the reset. Please get your car lead checked before doing any of this.

My tomtom go 910 will not switch on it has the green light on at the top left when plugged into a charger but nothing turns on when pressing button for 2 seconds any ideas??

In general I find these sort of problems can be fixed by the below

If the Tomtom loses battery power it might cease to function with a blank screen but will show a green light when you charge it. The trick is charge it on the mains charger for at least two hours. Then reset the device with a paper clip. If you get no reponse hold down the on button for at least 20 secs and the device will show the Tomtom logo and play a drum roll and startup normally.

Tomtom 910 problem

Hummm, this is a tough one...

1: Can you see the device in win explorer?
If yes, try to run "chkdsk /f" in a dos prompt.

2: Do you have a working backup?
Then you can format the internal drive through Windows or similar. Format with FAT32, the reinstall backup.

3: Run the Clear Flash tool:


3: Still no joy?
Then maybe send it in for repair, or buy a new one?

Tom tom 300

If the unit is still under warranty, send it back to Tomtom. Even if the unit is no longer under warranty, complain to Tomtom. There is a problem with the CLA (cigarette lighter adapter). It can cause internal damages to your Tomtom. What happens is that there are three wires in the CLA along with a voltage stepdown circuit board. The wire are +, -, and a signal wire. If the signal wire get disconnect the voltage could spike up to 12vdc. The unit is designed for only 5vdc.

If the unit is out of warranty then try the following website for repairs. They can fix the two chips which usually blows.
