My garmin 340 suddenly stopped working

Question

I have Garmin Street Pilot 340 model, without using the charger, i just used only the display unit to go 2 miles on the car.Suddenly it said "low battery" and it stopped working suddenly. And I tried to restart it once again by clicking the power button, even then it stopped working and not turning on.Can anyone please help me how to get it back and make it work.
