Thread: nuvi 58LM is working but not recognized by Computer

My Nuvi 58 currently has software 3.50 and here I got 4.60 the latest software that came out. Is it possible to install this software via SD card. That would be the simplest solution for my problem and maybe it would fix the connection problem if not I can patch it to this software and insert the unlocked maps on the SD card. That it worked, it definitely reads the SD card because I inserted the unlocked maps into the slot with the radars and it offered to copy the radars to it, but it didn't read the maps because it wasn't unlocked, it showed that it couldn't unlock maps, like non-patch devices.
