Its not wanting to charge up with usb and there is a lightning bolt sign through the battery in top right hand corner. wHAT COULD BE THE PROBLEM

It should take under 6 hours for a full charge.

Sounds like either it set a memory or the battery is bad. Let the phone totally die and then try to charge. If it want charge then, get a replacement battery

This means it's not getting a charge. I've just experienced this problem myself. I followed instructions online regarding cleaning lint from the charging port of the phone. Still no charge. I bought a charging cable that came with a car charger made by Belkin, this worked in the car, also allowed me to charge the phone from the pc, but wouldn't charge from the original plug. So I purchased an original Apple branded lightning cable today and it works. At last. So it turns out that my cable was faulty and another branded cable would not work with the Apple plug. So you need to try a known working Apple cable and plug and failing that clean out the port on the phone as lint is a common problem.

im not sure but may have somthing to do with the battery

Your question was posted under the Nuvi 680 GPS, so I am assuming this is the model that you have.

On the main screen, you will see a green battery status indicator in the upper right-hand corner of the screen. The battery is divided into 4 parts. Each part represents 1/4 power. So if you have one green bar, that indicates that the battery has 1/4 of power left. If there are 3 bars, that indicates that there is 3/4 power left.

When the unit is charging, you will see a yellow lightning bolt appear over the green battery status icon.

When the lightning bolt is not there, this means the unit is running off of the battery.

When leaving the unit to charge, press and hold the power button until you see that the screen says Charging Battery. A few seconds later, the screen will go blank to save energy.

Pressing the screen again later will either say Charging Battery or Battery Charge Complete.

slow flash yes trickle charge. fast flash is usualy not good. or orange led is bad.

Battery is probably junk. Find a friend with the same phone & test the phone before you buy a battery. You migh find a local phone store that will check the phone before you buy a new battery. Otherwise its ebay. Don't spend too much as these were not the best phones even when new.
Good luck, Bob

Horizontal lightning blot = OK = the battery is already fully charged

Vertical lightning blot = enough power for charging not getting to player - your USB port may be less than 2.0, or may be malfunctioning for some reason - try a different uSB port first - if still the same result, go into the Device Manager and make sure there is not a yellow exclamation mark by the USB port.

Use the wall charger if it will no longer charge via USB.

I would say make sure you are in the right USB port. My laptop has 3 and only one of them will charge my mp3 player
