Is there any updated maps that can be installed ?
If it's a later model 3790 it will be LM (Lifetime Maps) model. Connect it to GarminExpress to see what you are offered.

...... , what aas happened with the installed ones ?
The sound and roadnames is working when navigating in citys but no roadmaps ........
It might only need a hard reset/clear nonvol. Do you see anything at all on the screen, like the vehicle? Or is the screen completely blank, either black or white? If so there may be a problem with the screen or its connection to the board.
