I have an old Nuvi 760 and want to access the system files to change maps but they are not visible. This isn't a windows problem as my PC is permanently set to view hidden and system files. I therefore need to change MTP to mass storage in the settings, but how? I have spent ages googling this and can't find anything that works. The usual volume screen and speed meter presses do not work on this model.
