I am very sorry to hear that you are having problems with the unit. You may need to switch the unit on and press and hold the centre of the screen until the message ?No detailed maps? message disappears.
If your map detail is missing, then the map information may have been disabled. To check to see if the mapping has been disabled, follow the steps below:
From the Where to? and View Map page, touch the Spanner icon, settings (Tools). Touch Map. Touch Map Info. The unit should display the name of the map that is loaded to the unit. The box in front of the map name should have a tick in it. If it does not, touch the box to place a tick in it.
