One possible cause is that your battery is low or the battery can no longer hold a (good) charge. In this case, the TomTom is shutting down because there's not enough battery to keep it running, even though it is plugged into a power source.
To determine if the battery is the cause, try to charge the TomTom battery .... using a (USB) connection to your computer, or a direct power source (i.e. while the TomTom is not being used). Let it charge for a few hours until the batter charge indicator shows that it is fully charged (or just leave it charging overnight).
Then, unplug the TomTom from the "charger" and power it up. If the TomTom (battery) doesn't hold a (good) charge, the device will shut down within a few minutes, e.g. 10 mins or much less.
When you (then) plug the device into a power source, and it doesn't stay on (i.e. it keeps shutting down after 10 seconds), you can safely conclude that the battery is the cause of your problem.
The GPS device runs off the battery ... so, you need to charge the battery (fully, or enough to power the GPS) before you start using it again. For clarity, if the battery is not charged, the GPS will not run when plugged into a power source.
You can charge it through your computer. If you connect your satnav to your computer with the mini USB lead it will charge. A full charge takes about 8 hours.
You can charge through your car cigarette lighter socket either. This takes around 4 hours. The first charge should be continuous until it's charged so you might be better using your computer. After that if you plug it into the car it might be enough to keep it topped up depending on how much you use it.
NOTE: Don't start the car with the satnav plugged in. Unplug it first and when you've started the car plug it in then as there may be a surge of power when the car starts which has destroyed many satnavs.
It is likely that your battery is low or nearly-dead, particularly if you haven't used your GPS for a while and it has not been plugged in (to be kept charged). That's why it doesn't start (even if it is plugged in when you're trying to start it up again now). Don't try to repeat the startup (too often) as it will mess up your sw / data (when your battery is low or half dead)
You'll want to plug it in (e.g. using your USB or wall adapter) for up to 24 hours or so, to charge the battery. Then start it up and keep it plugged in until your battery is fully charged.
If the battery is flat or dead it will never go on until you either
charge the battery or change it. Batteries have a life of 2-3 years if used correctly. That is charged using an AC source and definitely not
starting the engine while the unit is plugged in.
1. Ensure that the battery is fully charged.
2. Try with different battery to determine whether the issue is with the battery or with the GPS device.
Hi happyivan8 i know tomtoms answer to this problem is to plug it in to the computer for a few hours but thats not really a fix, just an added pain in the rear.
i have 2 of these and one worked good after i updated it but the other still has the same problem and will only start after i charge it via the usb cable or unplug and plug the battery back in.
try updating it through tomtom home but it may or mayneo solve the problem. if you have already tried the update and that didnt help, i dont know what else you can do other then use it for target practice like im going to.
you can get tomtom home HERE if you dont have it already!
Plug it into your computer using a USB cable and press the reset button. Once it resets, keep it plugged in and your computer turned on, until the battery is fully charged. Every so often, charge it. If the battery goes totally dead, it will create problems.
