Power the unit on and immediatly place your finger in one of the corners and hold it there. I believe it is the top right but if it doesnt work the first time try a different corner. This will reset the entire device and erase all settings.
The only reset I know of is to hold down the power on/off switch for 10 seconds or more and it will reboot the unit, then allow it to do a full start up in a few minutes. See if that solves your problem ! IT did on mine.
Roll down your window, then wait for an underpass or a bridge, proceed to throw the unit either at the cement wall or into the water, make sure there's no other drivers around you as well as any innocent bystanders walking in the area. It really helped me a lot. THANKS GARMIN
