Hi there and welcome
Can you tell me please which model Navman you have?
This is usually an issue with the Firmware, so I would first like you to do this please.
Remove the charger from the unit and hold the power button to off for 60 seconds.
Release, then connect the charger and try to turn on the Navman and see if it can now connect
Let me know the results please
