If you downloaded not nuvi7x5_regionfileonly__250.gcd so updater do not load it because it have wrong SW. You downloaded wrong file for other devices! Exe files was only for for Nuvi 700-710-750-760!!!
This is nuvi7x5_regionfileonly__250.gcd (it is absent in Perry archive):
And how do you use updater? It work only with RGN files which created from GCD with rgntool SW. Or you can simply rename nuvi7x5_regionfileonly__250.gcd to gupdate.gcd and put it in Garmin folder in device or on SD if possible.Code:Please Login or Register to see the links
