Question about Garmin Nuvi 680 GPS Receiver
Try reseting the nuvi, there is a reset button on the bottom or on the back, some models have it on the front under the display cover.
if that doesn't help the digitizer which is the part on top of the lcd display that registers the touch could have failed and may need to be replaced.
I haven't seen many garmin repairers, you might have to get in touch with garmin about it, check ebay for replacement parts but if I remember correctly garmin takes care of it and don't distripute much parts.

SOURCE: can't unlock my garmin nuvi 680
There is NO master reset code. Whoever told you this was wrong. You have to use your security location to unlock it. Otherwise, you have to send it in to Garmin with the original receipt from an authorized Garmin dealer. This is to prevent use of the unit in case of theft.
