Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
This could just be a temporary software issue that we can cure with a simple reset.. Or, it could be a damaged map or software file and we may need to upgrade the units software.
Lets try this reset first
Once reset, let me know if the device will start normally, if it does please remember to return here and click and submit a 5 star rating.. If this reset doesn't work please send a reply and let me know what happened, and then we can go through further steps as needed.
