  • Unlock maps

    Hi.
    I have a zumo with lifetime map updates. I thought I'd try to use the lifetime thingy with my Nuvi (which doen't have lifetime maps!!).
    I've tried a couple of things...downloaded the gmapprom from the zumo then used PGFT to unlock .img file. Also tried PGFT to unlock through basecamp. But when I copy to sd card (changing to gmapsupp) it doen't appear in the nuvi? what am I doing wrong?

    Self error!! Tried sd card that was working in Nuvi and voila!!. EITHER my other card wasn't recognised by Nuvi or it's because I was using a 64G sd card instead of a 32G?

      Hi !

      Which Nuvi do you have ?
      Most use NTU map, but older ones use NT maps.

        PGFT does not fully unlock the map file. You must use "gimgunlock_04", "GarminUnlockerAlternativev8.0.1".

        p.s.
        You may need to edit the firmware.. See the "UniversalFirmwarePatcherForProtectedGarminDev ices " utility.
