It could be that the unit is in the "GPS OFF" mode. Get into the main menu--go to "Set Up" hit "Enter" --go "System" and under GPS make sure it is on.
Also take out the SD card and use without it, see if it does not work,
If the above did not help, find out the version and get the latest update from Garmin website.
