GPS Repair Problems? Ask a GPS Technician for Answers ASAP
Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
The battery is replaceable, and a new battery can be purchsed inexpensively online, here: http://amzn.to/2bSXnNZ
ON the back cover you'll see a slot, insert a coin in that slot and give it a turn to open the battery compartment and you'll see where the battery is easily removed and replaced.
Do you need more help with this?
