Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems.
If you have not tried this already, please try a master reset of the device and let me know what happens.

If that does not work, then this would indicate the device has prematurely failed and would need to be replaced through Garmin under their one year warranty.
In that case you would need to contact Garmin at the link below to have them replace the defective device:
