I got TomTom for a birthday gift in January. I only used it twice. How long does it hold a charge and how do I recharge it? Need to know asap. Thank you.

One full charge will hold good for approximately 3 hours.If you got it in January, it is better to recharge it. There are two easy ways to charge it. I assume you have got two different cables with it. One connects directly to the car cigarette lighter/12V socket. The other cable can be connected to a USB port of a computer. Tom get charged while connected to the computer also. On the outside chance you did not get the cable or cannot find it go to this link below to get the cables.

Please note Tom charges through the same port (USB) as it connects to the computer, which is it at the bottom of the Unit.
