I just bought a Garmin Nuvi 750, with intention that it would the best. But i was wrong, it does not include my own

address, the maps are outdated, and when i called up them for the help they told me that they are going to charge me

extra to upgrade the maps, and the streets and locations near my hosue is around two, three years old. I am very

upset with my maps and I just want to upgrade them.
