Question about Garmin (010-00583-00) for nuvi 750/760/770
If the unit will connect to your computer you can try copying all files from one GPS to the other. Just be sure not to copy over the *.UNL file. That contains the unlock information for that specific device. This may get the unit running. If you get the error can not unlock maps after doing this try updating the map again. If the above fails please call Garmin for assistance. 1.800.800.1020
