Re: The screen will not switch on
If you plug your Tom Tom into your home computer, you should be able to tell if it's going to turn on. It will charge, plugged in to your computer. If it works that way, you can suspect your lighter/utility plu in the vehicle.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

SAMSUNG GALAXY S5 - NO POWER, BATTERY, CHARGING AND CHARGER ISSUES
No power, battery, charging and charger issues
This guide contains troubleshooting steps and advice to help resolve issues you may experience when attempting to charge the handset.
After performing each step, please test to see if the issue is resolved.
Battery not charging
Battery is not lasting long
Phone won't charge
Failure to charge
Display remains black or blank
Are you using the correct equipment?Make sure you are using an approved Samsung wall charger and USB charging cable. Other brands of charging accessories may have different voltage parameters and could cause charging issues when used with Samsung devices.
Have you charged your phone for longer than 30min?
Leave your phone plugged in to the charger for about 30min without powering on. In some cases, it may take slightly longer for your phone to charge.
Is the battery icon displayed on the screen when charging?
After charging your phone for a little while you should get a battery charging icon appear on the screen which will indicate that your battery is charging properly.
If the charging icon appears, leave your phone for a little longer before you try to switch your phone on.
If however, the screen is blank and nothing is displayed, follow the below troubleshooting steps.
Is the charging cable plugged into a USB port?
Some charging cables can disconnect from the wall outlet adapter and plug directly into a USB port. However, when plugged into a USB port, the charging process is much slower due to the limited power output of USB ports. Instead, plug the device directly into a wall outlet to speed up the charging process.
Is the outlet faulty?
Try a different outlet or check for a switch connected to the outlet. If possible, try powering a different device on the same outlet.
Does another USB cable, or wall charger work?
Charging issues can occur if either the battery or charging cable is damaged. Verify that the charging contacts are clean. If necessary, clean the contacts using a cotton swab and rubbing on isopropyl alcohol.
If possible, test the charging cable by plugging it into another device and seeing if the device charges. Alternatively, try charging the device with a different cable. This may mean changing out the cable or the adapter on two-piece chargers.
If charging through a car charging kit, ensure that the car engine is running, and if possible try to charge other devices using other cables, through the same car kit. If none will charge, then it is likely there is a fault with the car charging kit. It is recommended to continue to cross-test devices, cables, and car kits until the problem device can be identified.
If the device charges when using a different USB cable or wall charger, the issue most likely lies with the charging accessory. In this case, follow the approved charger repair / replacement process.
Also, if the charger is connected via an extension or other multi-socket adapter, remove this and plug the charger directly into the wall-mounted socket. This will eliminate the possibility of a fault with the adapter.
If you are still unable to charge your device, continue to the next step.
Has the phone experienced any shock or exposure to water?
Accidental physical shock to a handset can sometimes cause problems to arise with battery or charger, as these components contain delicate parts, particularly. Damage can occur either to the component itself, or to the component's connection to the motherboard.
Water exposure can also lead to damage of these components, however due to the slow way in which this type of damage can manifest itself, the cause may not always be readily obvious.
With any physical damage of this nature, the only recourse is to contact the device manufacturer, and follow their approved repair or replacement process.
The charger has a function that restores the battery operation parameters by discharging then charging the battery a number of times. Refer to charging instructions in the pack but I think the cycle is a 3 hourly one, time to charge from a full discharge. If the charger thinks the battery is dead then it will try to recover the battery using this process. You may have left the charger on long enough to charge then also discharge the battery.
Start again and charge for the time in the instructions ONLY, if you are not sure of the time try it for an hour, then without disconnecting the charger turn the unit on and take particular note of any screen messages, if any.
You should be able to continue as normal now, but still be aware of the time you are leaving the charger connected for, as it may take some time before it returns to normal operation and stops trying to recover what it thinks is a dead battery.
I just don't think the battery is getting the charge due to a faulty piece that is between the Chargers plug and the handsets battery terminals, assuming the charger has been verified as a working one.
Thank you for your question.
If the battery icon on your screen is red, you need to charge your ipod immediately. Try charging it overnight. If it is not charged in the morning, there is a good chance your charger is dead.
Make sure the AC outlet you are plugging the charger into is definitely working. In some cases, you may need to bend the prongs on your charger just a little bit so they make better contact with the outlet.
If you have a car charger, or DC charger, try charging it in the car. If it works, your AC charger needs to be replaced.
If it doesn't charge, you may need to send your iPod in for service or take it to the Apple store.
Are you sure it was fully charged before? Could you see the full battery bars?
It sounds like your AC adapter (the charger) has likely gone bad. The phone battery probably wore down, and when you plugged it into the charger, the charger couldn't charge it, so the battery remained dead.
Since the battery is not charged, you can't turn the phone on at all when it's not connected to the charger. And when you do connect it to the charger and turn it on, you get the intermittent charging because something inside the adapter has a faulty connection -- sometimes it works, sometimes it doesn't.
You can easily verify if the charger is the problem by getting a new charger (they're not too expensive) and seeing if the phone will work and/or charge with the new charger.
If the new charger doesn't fix the problem, post again here and we'll go from there, but I think the new charger will take care of it.
i think you should take the car to a local parts house and have them to test the charging system . If the voltage regulator has stuck it could be pulling a constant draw on your battery also check at night to make sure that none of your lights are on sometimes the light switches can go bad and cause this to happen such as hood or trunk.Hope this has helped you out some!!
Vehicle Power Cable to the nüvi and connect the other end to your
computer, your nüvi does not operate as a GPS unit - it goes into some sort of charging mode. However, if
you FIRST turn on the nüvi in the battery mode then go
into the test mode (press the battery icon for about 8-9 seconds) from the main screen, THEN PLUG in the USB cable, and finally exit the test screen, your nüvi will restart (reboot) and it
will operate just like it was plugged into the cradle connection in your vehicle.
This mode will charge the battery AND operate as a GPS.
It works with my computer USB cable, my cell phone charger and my car charger for my cell phone.
Don't forget to turn off the nüvi before unplugging."
