Question about Garmin Nuvi 770 Car GPS Receiver
Your device freezed that is why it is stuck on the garmin screen. You need to first reset your garmin by holding the power on/off button for about 15 seconds, that way it will restart.
About the battery, when you get a new battery for your device, you need to charge it for about 3 hours before powering on, once you power on without charging it first, then it might kill the cells of the battery as they are lithium ion battery. What you have to do is to remove the battery, insert it back, then you plug it to a power source for about 3 hours, be sure that the battery is charging as the green light comes on as you plug it. If the green light does not come on, then you need to connect it to a computer using your USB cable, that way it will charge. Once it is charged for about 3hours, then you will be able to turn on your device. First reset, then charge battery. That should do the job for you.
Hope this information was helpful.
