To avoid an eventual loss of power while you are driving and the subsequent unsafe fumbling with the machine, you can plug the TT in the cigarette lighter during your ride. This will supply power to the GPS and recharge the battery. Alternatively, before going on a trip plug the TT in a USB port of a computer and it will recharge the battery. With a fully charged battery and the car power adapter/battery charger you will not run out of power.
Power on the TT 910 and then press the Reset Button on the base of the TT. It is a tiny hole with a hidden button. use a rounded object, match end or soft pencil to puch the button. Then reconnect it to the PC and the PC will see the TT. Note that you may have to reload apps and maps depending on the state of the TT.
More than likely the negative post on your 910 is not making a contact. This is a known problem for the X10 series tt's. It can be fixed but you have to disassemble the tt to do it. No just replacing the battery won't fix your problem. If it was just a battery problem your tt would still boot up if connected to external power.
You don't say what kind of tt you have but most have a reset hole on the bottom of the device. Take a paperclip and straighten one side out. Insert the paperclip into the reset hole and hold it for at least fifteen seconds. Your tt should start normally after that. If it doesn't start up you may have the green light of death and nothing you do will get it going again.
Hope this helps
If you are not bothered about using it on battery your tt should work if you have it hooked up to a external power supply such as the car charger or home charger. If it doesn't work using either of the power supplies then your problem is deeper than just needing a new battery. Check the pins on the bottom of your tt to see if they are bent, or out of place. The most common problem for them is the negative pin on the far left with the lcd screen facing away from you gets bent or is not making contact even though the green light is on.
Hope this helps
I'm assuming you own a TT.. in which case, yes.. the CLA should have a fuse. I wouldn't recommend replacing the fuse yourself in case you get the amps wrong and burn out your TT. check that the green light on the CLA comes on.. if not, then you probably don't have the CLA in right. Otherwise, you can purchase a replacement TomTom CLA online somewhere.
You definitely need software and maps on an SD card. The TOMTOM will not work without a card inserted. The card will contain MAPS , Map authorisation codes ( to show they are genuine TOMTOM maps bought and paid for ) , POI ( points of interest ), GPS fix data , voices ( for spoken navigation ) etc etc etc. ....................
PLEASE NOTE , TRYING A CARD FROM ANOTHER TOMTOM is very unlikely to work. Each card has an authorisation code that is generated via an algorithm inside each TOMTOM and is device specific.
However , trying a card from another tomtom might produce a diferrent result but still not work , at least this might prove that the tomtom is working OK before you rush out and buy a tomtom card.
My daughter had this problem and it actually turned out to be the cigarette lighter connection. The fuse needed changing and bingo all working well now! Check you have a green light on the charger cable going into your cigarette lighter - if you dont its probably the fuse.
