Whilst updating the software using the instructions shown here:
http://www.nav-plus.com/instructions/software.html
I have managed somehow to cancel the download, leaving the screen "SM Graphic system - Loading data..." showing and the progress bar frozen.
Having switched off and switched on again, the screen information display does not work, and the TV is on all the time when the unit is switched on, though the radio stations can be changed (but there is no display to show which station it is. Nothing happens when I press any of the navigation buttons.
Can anyone suggest how to solve this please?
