Sandra Silveira, Of course, you should disassemble your Garmin and make sure that all the wires are okay. I would think that it is your digitizer that has failed. Follow [guide|4715|this guide] for the replacement. The digitizer is available at places [http://www.ebay.com/itm/LCD-Touch-Screen-Digitizer-Tactile-Garmin-Nuvi-680-660S-/320684663933|like this] and [http://www.mylcdtouchscreen.com/garmin-nuvi-680-touch-screen-digitizer-glass-replacement_p432.html|on here.] Hope this helps, good luck.
